907507886d (wall, native)_clock: Add GetGPUTick
Allows us to directly calculate the GPU tick without double conversion to and from the host clock tick.

bff1453282 core_timing: Use higher precision sleeps on Windows
The precision of sleep_for and wait_for is limited to 1-1.5ms on Windows.
Using SleepForOneTick() allows us to sleep for exactly one interval of the current timer resolution.
This allows us to take advantage of systems that have a timer resolution of 0.5ms to reduce CPU overhead in the event loop.

b2ad4dd189 common/x64: Use TSC clock rate from CPUID when available
The current method used to estimate the TSC is fairly accurate - within a few kHz - but the exact value can be extracted from CPUID if available.

6267110b69 common: wall_clock: Check precision against the emulated CPU and CNTFRQ
In addition to requiring nanosecond precision, using the native clock requires that the hardware TSC has a precision greater than the emulated CPU and its clock counter.

3acb265c9e common: wall_clock: Fix integer overflow with StandardWallClock.
- Previous optimized impl. resulted in an integer overflow, so revert.
- This is our slow/fallback path that should never be really be used, so the optimization in unimportant.

771a9c21cc common/wall_clock: Add virtual destructors
From -fsanitize=address, this code wasn't calling the proper destructor.
Adding virtual destructors for each inherited class and the base class
fixes this bug.

While we are at it, mark the functions as final.
