Morph 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.

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

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 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).

Lioncash a7af349dae core_timing: Make use of uintptr_t to represent user_data
Makes the interface future-proofed for supporting other platforms in the event we ever support platforms with differing pointer sizes. This way, we have a type in place that is always guaranteed to be able to represent a pointer exactly.

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.

Fernando Sahmkow 90792cdb6e Core_Timing: Make core_timing threadsafe by default.
The old implementation had faulty Threadsafe methods where events could
be missing. This implementation unifies unsafe/safe methods and makes
core timing thread safe overall.

Lioncash c5d41fd812 core/core_timing: Make callback parameters consistent
In some cases, our callbacks were using s64 as a parameter, and in other
cases, they were using an int, which is inconsistent.

To make all callbacks consistent, we can just use an s64 as the type for
late cycles, given it gets rid of the need to cast internally.

While we're at it, also resolve some signed/unsigned conversions that
were occurring related to the callback registration.

Lioncash bd983414f6 core_timing: Convert core timing into a class
Gets rid of the largest set of mutable global state within the core.
This also paves a way for eliminating usages of GetInstance() on the
System class as a follow-up.

Note that no behavioral changes have been made, and this simply extracts
the functionality into a class. This also has the benefit of making
dependencies on the core timing functionality explicit within the
relevant interfaces.

Lioncash 48d9d66dc5 core_timing: Rename CoreTiming namespace to Core::Timing
Places all of the timing-related functionality under the existing Core
namespace to keep things consistent, rather than having the timing
utilities sitting in its own completely separate namespace.

core_timing: Don't include the log header in core timing's header
Avoids propagating logging macros and facilities to files that may not need them.
This also allows hiding an internal constant.

core: Replace remaining old non-generic logger usages with fmt-capable equivalents
LOG_GENERIC usages will be amended in a follow-up to keep API changes separate from
interface changes, as it will require removing a parameter from the relevant function
in the VMManager class.
