This implements MWAITX and WAITPKG extensions (umonitor, mwait) for CPUs that support them.
Reduces wait times and bypasses the timing stuff from the OS that is slow (windows notably). generally it should answer within 0.2 to 0.5 microsecs (since most requests wait for that long).
Also does a general rework of static ctors and stuff

---------------
Hello,
I am submitting a small fix to prevent an unintended abort when _GLIBCXX_ASSERTIONS is enabled, caused by out-of-bounds access in debug logging.
Background / Issue
In the server-side implementations of ITimeZoneService::ToPosixTime and ToPosixTimeWithMyRule, the SCOPE_EXIT debug logging previously accessed out_times[0] and out_times[1] unconditionally.
However, out_times is an IPC-provided output buffer (OutArray, which inherits from std::span). Its length depends on the caller-provided buffer capacity. During debugging, I encountered a case where out_times.size() == 1.
Under _GLIBCXX_ASSERTIONS, accessing out_times[1] triggers a std::span::operator[] assertion failure (std::__glibcxx_assert_fail) and aborts the process, causing the service thread to crash. This results in an unintended crash caused solely by debug logging.
Change Description
In the SCOPE_EXIT logging blocks of both ToPosixTime and ToPosixTimeWithMyRule, I added bounds checks before accessing out_times[0] and out_times[1]:
Access out_times[0] only if out_times.size() > 0
Access out_times[1] only if out_times.size() > 1
Print 0 when the corresponding element is unavailable
This change only affects debug log output. It does not modify IPC semantics or the time conversion logic itself.
Reproduction Context (for reference)
I encountered this issue while running 13 Sentinels: Aegis Rim (title ID: 01008D7016438000). During the “Load Game” flow, ToPosixTimeWithMyRule is invoked with an out_times buffer of length 1, which previously led to the out-of-bounds access in the logging code.
Thank you for your time and review.
Best regards,

- use std::optional instead of std::unique_ptr for the Antialias (FXAA, etc) passes to avoid the extra deref
- use a pattern for deferencing the IR pointer chasing loop as suggested on the intel optimization manual
- this also removes std::vector<> overhead by using boost::container::small_vector<> (not a silver bullet but in the case of this function reduces access times)

Adds fully functional overlay display.
- Enable Overlay Applet via "View" -> "Enable Overlay Display Applet"
- Open the overlay by pressing the home button for over 1s
- Can adjust volume
- Can toggle airplane mode (if on WiFi, maybe if overlay is enabled pretend to be on WiFi?)
- Future TODO(?): Adjust Brightness implementation for host system
- Inputs are properly registered. e.g. if overlay open, application does not register inputs.
You can control volume and airplane mode outside of the emulator window
