c3fbc8d2fe core_timing: Remove GetCurrentTimerResolution in CoreTiming loop 
Other programs may change this value, but if thousands of syscalls in this loop is undesirable, then we can just set this once.

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

8e56a84566 core_timing: Use CNTPCT as the guest CPU tick 
Previously, we were mixing the raw CPU frequency and CNTFRQ.
The raw CPU frequency (1020 MHz) should've never been used as CNTPCT (whose frequency is CNTFRQ) is the only counter available.

e1bce50d8b core_timing: Make use of MicroSleep for x64 CPUs 
For CPUs that support tpause, this should result in significant CPU power savings over thread yield in this spin wait.

3053a62375 core: Promote CPU/GPU threads to time critical 
And also demote Audren and CoreTiming to High thread priority.

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.

This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

ebb64d5bf4 core: Resolve misc cases of variable shadowing 
Resolves shadowing warnings that aren't in a particularly large
subsection of core. Brings us closer to turning -Wshadow into an error.

All that remains now is for cases in the kernel (left untouched for now
since a big change by bunnei is pending), and a few left over in the
service code (will be tackled next).
