hid: Implement ReloadInputDevices

service: Remove unused g_kernel_named_ports variable

With the named port functionality all migrated over to the kernel,
there's no need to keep this around anymore.

shader_decompiler: Implemented TMML

GPU/DMA: Partially implemented the 'enable_2d' bit in the DMA engine.

video_core: fixed arithmetic overflow warnings & improved code style

shader_decompiler: Implemented (Partialy) TXQ

- Fixed all warnings, for renderer_opengl items, which were indicating a
possible incorrect behavior from integral promotion rules and types
larger than those in which arithmetic is typically performed.
- Added const for variables where possible and meaningful.
- Added constexpr where possible.

Externals: Update xbyak

When not set, this tells the GPU to only use the X size when performing a DMA copy.
This is only implemented for linear->linear and tiled->tiled copies. Conversion copies still retain the assert.

This bit is unset by some games for various purposes, and by nouveau when copying the vertex buffers.

Initial support for non-2D textures

yuzu: fix title bar display

audio_renderer: Rename AudioOut instance to audio_out

Previously the version number got hidden after starting a game.

gl_rasterizer: Use baseInstance instead of moving the buffer points.

yuzu: Move GameListWorker to its own source files

This hopefully helps our cache not to redundant upload the vertex buffer.

* video_core: Arithmetic overflow fix for gl_rasterizer

- Fixed warnings, which were indicating incorrect behavior from integral
promotion rules and types larger than those in which arithmetic is
typically performed.

- Added const for variables where possible and meaningful.

* Changed the casts from C to C++ style

Changed the C-style casts to C++ casts as proposed.
Took also care about signed / unsigned behaviour.

- Will not work for non-2d textures, and was not used anyways.

core: Migrate current_process pointer to the kernel

f1babc8 externals: Update catch to 2.3.0
a0c587a A32/decoder: Add missing <algorithm> includes

This has gotten sufficiently large enough to warrant moving it to its
own source files. Especially given it dumps the file_sys headers around
code that doesn't use it for the most part.

This'll also make it easier to introduce a type alias for the
compatibility list, so a large unordered_map type declaration doesn't
need to be specified all the time (we don't want to propagate the
game_list_p.h include via the main game_list.h header).
