Morph 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.

Morph 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.

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

Morph 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.

Lioncash 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).

core_timing: Use better reference tracking for EventType. (#3159) 
* core_timing: Use better reference tracking for EventType.

- Moves ownership of the event to the caller, ensuring we don't fire events for destroyed objects.
- Removes need for unique names - we won't be using this for save states anyways.
