Prepare frontend for multiple graphics APIs (#6347)

Browse source 
* 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
