CMakeLists: Add architecture detection for AArch64

common: Remove unused old breakpoint source files

We already have an equivalent in place for the 32-bit ARM architecture, so we
should also have one for the newer 64-bit ARM architecture as well.

These currently aren't used and contain commented out source code that
corresponds to Dolphin's JIT. Given our CPU code is organized quite
differently, we shouldn't be keeping this around (at the moment it just
adds to compile times marginally).

audout_u: Correct IAudioOut initializer list order

Fix BC7U

renderer_opengl: Implement RenderTargetFormat::RGBA16_UNORM.

logging/backend: Use const reference to refer to log filter

The filter is returned via const reference, so this was making a
pointless copy of the entire filter every time a message was being
pushed into the logger instance.

Added missing channel devices

Orders elements in the precise order they'll be initialized.

- Used by Breath of the Wild.

Implement RG32UI and R32UI

audio_core: Interpolate

arm_dynarmic: Remove IsExecuting check from PrepareReschedule

maxwell_to_gl: Implement VertexAttribute::Size::Size_8.

No longer required. HaltExecution is a no-op if it is not currently executing.

Needed for xenoblade

vfs: Use sanitized paths within MoveFile() and MoveDirectory()

card_image: Simplify return statement of GetSubdirectories()

kernel/object: Tighten object against data races

- Used by Breath of the Wild.

renderer_opengl: Implement RenderTargetFormat::RGBA16_UINT.

Despite being covered by a global mutex, we should still ensure that the
class handles its reference counts properly. This avoids potential
shenanigans when it comes to data races.

Given this is the root object that drives quite a bit of the kernel
object hierarchy, ensuring we always have the correct behavior (and no
races) is a good thing.

- Used by Breath of the Wild.

renderer_opengl: Implement RenderTargetFormat::RG8_UNORM.

maxwell_to_gl: Implement PrimitiveTopology::LineStrip.

- Used by Breath of the Wild.

- Used by Breath of the Wild.

Use an approximated amortized amount of ticks when advancing timing.

scheduler: Make HaveReadyThreads() a const member function

Fixed a bunch of race conditions when running in multicore mode.

Kernel/Mutex: Don't duplicate threads in the mutex waiter list.

gl_shader_decompiler: Implement XMAD instruction.
