This doesn't depend on class state and can just be a regular function.

Keeps the implementation internalized and also reduces API-facing header
dependencies.

Notably, this fully internalizes all of the xbyak externals.

Given it's intended to be an internal implementation class, we can move
it into the cpp file to ensure that.

This also lets us move some header dependencies into the cpp file as
well.

Improve FFmpeg cmake file

yuzu: Add volume hotkeys

* Fix compilation if CUDA_INCLUDE_DIRS is empty/contains multiple paths
* Pass CMAKE_{C,CXX}_COMPILER_LAUNCHER to ffmpeg compiler

input_common: Report battery for UDP controllers

Various fixes to HLE service thread management

service: apm: Stub ISession SetCpuOverclockEnabled

- But do not enter the priority queue, as otherwise they will be scheduled.
- Allows dummy threads to use guest synchronization primitives.

service: Update function tables

Switchbrew has the function names now.

Use Default Colorful theme by default outside of Windows

shader_recompiler: fix potential OOB access

On OSes with system-wide theming this allows yuzu to follow system style, regardless of its exact coloration, working well with both light and dark system themes. Dark /Colorful, on the other hand, forces dark theme regardless of user preferences set in system settings, making for a poor default.

Use Colorful variation to keep in line with icon style of patron-voted Dark Colorful.

Since we don't currently support CPU overclocking within the emulated system, this can be stubbed for now, like APM IsCpuOverclockEnabled.

- Used by Gravity Rider Zero

common: bit_util: Add IsPow2 helper function

- These are already tracked by kernel's registered_objects member.

- This does not appear to be necessary anymore.

- Considering is_thread_waiting is never set, so we can remove IsThreadWaiting.
- KThread::EndWait will take the scheduler lock, so we can remove the redundant lock.

- These are only used by host threads for locking and will never have a wait_queue.

- These are only used by host threads for locking.

- This will be used to ensure that we do not schedule dummy threads.
