RedBlackAka 2a66b40267 [common/cpu_detect] Remove SSE/SSE2/FMA4/AVX_VNNI detection (#3979)
Removes Eden's own feature detection for SSE, SSE2, FMA4 and AVX_VNNI, in order to clean up code and make the function slightly lighter. They are all unused and I have specific reasons for their removal:
- SSE/SSE2 are always true for x64
- FMA4 is a deprecated AMD exclusive extension, replaced by the regular FMA and was logged here as "FMA" for no reason
- AVX_VNNI simply does not seem applicable for Eden (but can still be checked for through Xbyak's feature detection if necessary)

lizzie 395613b01f [common/logging] Simplify logging logic and fix issues when logging before system is created (#3688)
- our logging code was bigger than spdlog itself, why???? just keep it simple
- fix issues when logging before logging system is even started
- removes the "initialized logging twice" issue
- removes uneeded indirection in file logging
- uses direct formatting instead of jumping hoopla-around the fmt::format() ressult
- code duplication and dead code removal as usual

I did explore dup2() but I think it's not worth the hassle
I did try `fwopen()` but it's better if things are just kept as-is.

there is a lot of noise because I removed a bunch of redundant files on logging and just put everything in one file

now normally this wouldn't be a good idea, however consider: the complexity of logging; it's less than 500 lines... does it really need a whole subsystem?!?!?! ITS JUST LOGGING

Wunkolo c802f8fbd2 cpu_detect: Add additional x86 flags and telemetry
Adds detection of additional CPU flags to cpu_detect and additions to telemetry output.

This is not exhaustive but guided by features that [dynarmic utilizes](https://github.com/merryhime/dynarmic/blob/bcfe377aaa5138af740e90af5be7a7dff7b62a52/src/dynarmic/backend/x64/host_feature.h#L12-L33) as well as features that are currently utilized but not reported to telemetry(invariant_tsc). This is intended to guide future optimizations.

AVX512 in particular is broken up into its individual subsets and some other processor features such as [sha](https://en.wikipedia.org/wiki/Intel_SHA_extensions) and [gfni](https://en.wikipedia.org/wiki/AVX-512#GFNI) are added to have some forward-facing data-points.

What used to be a single `CPU_Extension_x64_AVX512` telemetry field
is also broken up into individual `CPU_Extension_x64_AVX512{F,VL,CD,...}` fields.

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.
