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.

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).

Port #3804 from Citra - Better Title Bar Display

Given we now have the kernel as a class, it doesn't make sense to keep
the current process pointer within the System class, as processes are
related to the kernel.

This also gets rid of a subtle case where memory wouldn't be freed on
core shutdown, as the current_process pointer would never be reset,
causing the pointed to contents to continue to live.

file_sys/{nca_patch, patch_manager}: Amend unnecessary/missing includes.

frontend: Set swap interval to 0

core/core: Remove unnecessary sm/controller include

video_core/CMakeLists: Add missing gl_buffer_cache.h

video_core/gl_buffer_cache: Minor tidying changes

gl_rasterizer: Call state.Apply only once on SetupShaders.

gl_shader_decompiler: Implement saturate mode for IPA.

Ensures that the cache always has a deterministic initial state.

GetHandle() internally calls GetHandle() on the stream_buffer instance,
which is a const member function, so this can be made const as well.
