Partially implement Indexed samplers in general and specific code in GLSL

GUI: Deadzone controls for sdl engine at configuration input

hid: Fix analog sticks directional states

core/arm: Remove usage of global GetCurrentThread()

kernel/physical_core: Make use of std::unique_ptr instead of std::shared_ptr

Revert "system_archive: Fix Korean and Chinese fonts"

Now both CPU backends go through their referenced system instance to
obtain the current thread.

shared_ptr was used in 2d1984c2 due to a
misunderstanding of how the language generates move constructors and
move assignment operators.

If a destructor is user-provided, then the compiler won't generate the
move constructor and move assignment operators by default--they must be
explicitly opted into.

The reason for the compilation errors is due to the fact that the
language will fall back to attempting to use the copy constructor/copy
assignment operators if the respective move constructor or move
assignment operator is unavailable.

Given that we explicitly opt into them now, the the move constructor and
move assignment operators will be generated as expected.

Nothing from these headers are used within this source file, so we can
remove them.

This isn't used within the class, so it can be removed to simplify the
overall interface.

While we're in the same area, we can simplify a unique_ptr reset() call.

System: Refactor CPU Core management and move ARMInterface and Schedulers to Kernel

system_archive: Fix Korean and Chinese fonts

 shader/memory: Implement LDL.S16, LDS.S16, STL.S16 and STS.S16

shader/memory: Implement ATOM.ADD

texture_cache/surface_base: Fix layered break down

gl_texture_cache: Silence implicit sign cast warnings

gl_shader_decompiler: Remove UNIMPLEMENTED for gl_PointSize

This was implemented by a previous commit and it's no longer required.

GUI: dark themes refinements and QSS cleanup

gl_texture_cache: Properly implement depth/stencil sampling

bsd: Stub several more functions.

Layered break downs was passing "layer" as a "depth" parameter. This
commit addresses that.

This addresses the long standing issue of compatibility vs. core
profiles on OpenGL, properly implementing depth vs. stencil sampling
depending on the texture swizzle.

This commit instends on better naming the new purpose of this classes.

ATOM operates atomically on global memory. For now only add ATOM.ADD
since that's what was found in commercial games.

This asserts for ATOM.ADD.S32 (handling the others as unimplemented),
although ATOM.ADD.U32 shouldn't be any different.

This change forces us to change the default type on SPIR-V storage
buffers from float to uint. We could also alias the buffers, but it's
simpler for now to just use uint. While we are at it, abstract the code
to avoid repetition.

This commit moves ARM Interface and Scheduler handling into the kernel.
