CamilleLaVey ed566919f4 [vulkan, android] Add feature of post-processing shaders on Android (#4348)
Very self-explanatory; implementation of the feature for post-processing shaders for Android (at least for now); will allow users to enhance the graphic quality of video games based on the use of multiple shaders adjustable, presets and more, inspired on the PPSSPP implementation, this feature adds 22 customizable shaders (1 pass) that lives on the overlay of the screen, which means that aside of the capability to chain multiple shaders on the screen, this doesn't have depths (pixel/ depth z-buffer) so it ensures the performance with it's use. Few shaders were a faithful port from PPSSPP with their respective attribution on the shader headers for their respective owners; and there are adaptations from public references/ cinematographic (Anime4K) and the rest are my own addition.

_Special Credits:_

CamilleLaVey a538cd9aff [shader_recompiler, vulkan] Virtual buffer pages with multi-range + sparse buffers binding (#4362)
Storage buffers can span GPU pages that aren't contiguous in host memory, but the buffer cache assumed one contiguous buffer per binding, so anything crossing a mapping boundary read the wrong bytes. Multi-range binding resolves the real segments and presents them to the shader as one buffer, aliasing their memory into a sparse VkBuffer or gathering them into a copy, all of this was mostly fixed by making a path to use sparse on buffers (the same way as texture cache has it) and retrieve properly the mapping ranges to the virtual pages, including the actual structure on the use of binding sparse.

Meanwhile this fixes Monster Hunter Sunbreak z-fighting, bad performance and mostly vertex explosions (coming from the contiguous buffer read from the shader's game) it's only the basis for a further investigation towards how are we gonna treat phi calculations, optimized them and mostly eradicate the currently excess of exposure on the textures where the lightning trace should not being reflected.

crueter 7fda6dde73 [common] Switch to boost::unordered_flat containers (#4326)
Replaces all instances of ankerl's unordered map/set with boost's
`unordered_flat_*` classes. This uses std::hash since boost::hash is
actually a lot slower.

Also adds an abstraction layer in `Common` so future changes are quicker
and easier.

Other implementation details:
- ankerl provided hash specializations for tuple and pair, so those were
  ported here
- std::erase_if doesn't work on boost, so just used the ADL'd erase_if

This should be about equal or superior performance as unordered_dense for everything except iteration.

Meanwhile the expected behavior was to reduce graphical issues (on games with Quad shaders reliant), we encountered a very slight performance increase depending on what game and shader are actually compiled.

In resume, rather than performance (due to the reduced amount of process on duplicated/ synced code on pipeline/texture cache), it's a graphica accuracy work that will improve image quality at the cost of almost 0 performance hit, rather than certain hitch if the color combination wasn't cached before.

CamilleLaVey 49a0ca6d5d [vulkan] Initial implementation on Bindless Buffer/Descriptors (#4251)
Adds a VK_EXT_descriptor_buffer, VK_KHR_device_buffer_address path alongside push descriptors and descriptor sets. The ring is chunked and sized from the device limits, so drivers with a small sampler range (QCOM reports 128 KiB) get more, chunks per frame instead of losing the feature. A pipeline uses one path or the other, never both, since some drivers do not support bufferless push descriptors. The chunk binding is only re-emitted when it changes, and a draw that repeats the previous payload reuses its allocation instead of rewriting it. This whole change will help to reduce the constant use of descriptors on the slower path, improves the "slow implementation" on QCOM drivers (A7xx and older) for push descriptors, improves latency when compiling pipelines. The implementation on indexing descriptors was also refined.

CamilleLaVey eb9280dedf [vulkan] 4th Vulkan Global Maintenance (#4212)
The approach on this PR moves around refactoring/ updating residual work; main issue was the whole logic behind msaa upload/download images with the constant image copy per pass required; which was gated via shaderStorageImageMultisample, which is not available on all the platforms supported including Android, making them to rely into a more heavier approach to convert msaa image copy into a non msaa image copy, not only losing precision in the conversion, but also creating bugs around the resolve of the image itself, if the supported path had to copy 2 times the same image to be actually presentable, when the fallback was enabled 3 copies were performed, not only decreasing the performance but also increasing race conditions due to the certain capabilities processed in this chain (storage_views). In order to resolve them more naturally, the constant copies were removed from the now "common" path along establishing a proper color resolve for Android and actually making them more direct.

Yet this opened a new pack of outdated handling on our current backend; since we now pass msaa images more directly (whenever a game request a msaa type of image/ which seems to be not common + each fragment resolves images on how it's actually required, adding missing depth/stencil), how we often load and store them becomes a critical issue, since our current configuration renderpass/framebuffer forces to always load and load clear whenever a new attachment it's passing through the renderpass, making this really heavier on memory bandwidth limited devices as SteamDeck and others that doesn't rely on the inmediate rendering mode (Tilers vs iGPU); to prevent over allocating data, I had to re-structure part of the current renderpass and framebuffer to actually reuse part of the data/ attachments called, with flags as DON'T_CARE, simplifying partially on how we actually call attachments including their barriers and conditions (occlusion, etc), the DON'T_CARE it's specifically useful to not only prevent calling new loads (which is a flush and heavier on tiler devices) and not only reusing the actual data store, which works on the future time, this saves memory bandwidth and gives space to actually avoid the constant pressure on SYSMEM/GMEM shader resolver path.

This maintenance also improved the current removal features logic on QCOM drivers, closing gaps between implementations on descriptors (VK_EXT_indexing_descriptor), adjusting the whole WMEL to avoid being so stricter if certain capabilities are missing to actually use this feature, leading to test and play more on how QCOM drivers are actually behaving; meanwhile the main objective is to open path for a robust and bigger implementation in the future, the changes made here also contains small bug fixes on SPIR-V logic, adding missing cases to resolve shaders (FP64 -> FP16), adding more robustness on how narrow features are actually being used and how to wired them whenever they're not available, meanwhile there are still some issues in regards on how Tegra vs Adreno can preserve unorms at FP32 and FP16, leaving better understanding on base for what VK_EXT_shader_float_controls is actually doing most of the times (flushes NaN's and Denorms equally).

MaranBr a27d35463e [video_core] Improve synchronization and refactor buffer cache timing logic (#4182)
This simplifies the GPU accuracy setting by removing the intermediate Balanced mode and setting High as the default on desktop platforms.

It introduces a dedicated setting for GPU fence behavior, allowing the synchronization policy to be configured independently of GPU accuracy.

The Vulkan buffer cache now tracks GPU recording timeline ticks and waits only when necessary, reducing unnecessary synchronization while maintaining correctness for hard-to-trace graphical bugs.

GPU buffer readback has also been refined to synchronize only the affected upload regions when needed, and default DMA behavior has been updated to align with the new GPU accuracy model.

### TL;DR

The fix for particles freezing and unfreezing in mid-air in `Super Mario Odyssey` has been improved, resulting in less of a performance hit.
This game requires the new `Enable GPU Buffer Readback` option to be enabled to fix this issue.

The vertex explosions that occurred in `Super Mario Bros. Wonder`, especially in World 4, have been completely eliminated. You can now enjoy a smooth experience without graphical glitches exploding across the screen.
This game requires the new `GPU Fence Behavior` option to be set to `Strict` to fully fix this issue.

The flickering issue inside certain Shrines in `The Legend of Zelda: Tears of the Kingdom` has also been fixed.
For now, this game requires the new `GPU Fence Behavior` option to be set to `Accurate` to fully fix this issue.

These options are intended to fix graphical bugs in games that require better synchronization behavior between CPU and GPU, so other games may be affected as well.
