* externals: Update dynarmic
* settings: Introduce GraphicsAPI enum
* For now it's OpenGL only but will be expanded upon later
* citra_qt: Introduce backend agnostic context management
* Mostly a direct port from yuzu
* core: Simplify context acquire
* settings: Add option to create debug contexts
* renderer_opengl: Abstract initialization to Driver
* This commit also updates glad and adds some useful extensions which we will use in part 2
* Rasterizer construction is moved to the specific renderer instead of RendererBase.
Software rendering has been disable to achieve this but will be brought back in the next commit.
* video_core: Remove Init/Shutdown methods from renderer
* The constructor and destructor can do the same job
* In addition move opengl function loading to Qt since SDL already does this. Also remove ErrorVideoCore which is never reached
* citra_qt: Decouple software renderer from opengl part 1
* citra: Decouple software renderer from opengl part 2
* android: Decouple software renderer from opengl part 3
* swrasterizer: Decouple software renderer from opengl part 4
* This commit simply enforces the renderer naming conventions in the software renderer
* video_core: Move RendererBase to VideoCore
* video_core: De-globalize screenshot state
* video_core: Pass system to the renderers
* video_core: Commonize shader uniform data
* video_core: Abstract backend agnostic rasterizer operations
* bootmanager: Remove references to OpenGL for macOS
OpenGL macOS headers definitions clash heavily with each other
* citra_qt: Proper title for api settings
* video_core: Reduce boost usage
* bootmanager: Fix hide mouse option
Remove event handlers from RenderWidget for events that are
already handled by the parent GRenderWindow.
Also enable mouse tracking on the RenderWidget.
* android: Remove software from graphics api list
* code: Address review comments
* citra: Port per-game settings read
* Having to update the default value for all backends is a pain so lets centralize it
* android: Rename to OpenGLES

We are going to add private memebers to ShaderSetup, which forbids the usage of offsetof. The JIT program only use the uniform part of the setup, so we can just isolate it.
Optimize AttributeBuffer to OutputVertex conversion
First I unrolled the inner loop, then I pushed semantics validation
outside of the hotloop.
I also added overflow slots to avoid conditional branches.
Super Mario 3D Land's intro runs at almost full speed when compiled with
Clang, and theres a noticible speed increase in MSVC. GCC hasn't been
tested but I'm confident in its ability to optimize this code.
Among four shader units in pica, a special unit can be configured to run both VS and GS program. GSUnitState represents this unit, which extends UnitState (which represents the other three normal units) with extra state for primitive emitting. It uses lots of raw pointers to represent internal structure in order to keep it standard layout type for JIT to access.
This unit doesn't handle triangle winding (inverting) itself; instead, it calls a WindingSetter handler. This will be explained in the following commits
One of the later commits will enable writing to GS regs.
It turns out that on startup, most games will write 4096 GS program words.
The current limit of 1024 would hence result in 3072 (4096 - 1024) error messages:
```
HW.GPU <Error> video_core/shader/shader.cpp:WriteProgramCode:229: Invalid GS program offset 1024
```
New constants have been introduced to represent these limits.
The swizzle data size has also been raised. This matches the given field sizes of [GPUREG_SH_OPDESCS_INDEX](https://3dbrew.org/wiki/GPU/Internal_Registers#GPUREG_SH_OPDESCS_INDEX) and [GPUREG_SH_CODETRANSFER_INDEX](https://www.3dbrew.org/wiki/GPU/Internal_Registers#GPUREG_SH_CODETRANSFER_INDEX) (12 bit = [0; 4095]).
