Of it, the backends read the EFB scale, now passed as the backbuffer
scale; GLContext::Create tested for libretro, its only context; and
the controller interface kept a render window that is always null. The
video backends' Initialize, InitBackendInfo and PopulateBackendInfo,
Core::Init, EmuThread and StartEmuThread, BootCore and the controller
interface lose the parameter; PrepareWindow, ChangeWindow, the window
change refresh and the Vulkan instance's surface extensions go, as
nothing presents but the frontend.
Each backend's are final and called by the backend in use; the Null
backend uses the base classes, which count nothing. Bounding box values
are read into and written from the caller's arrays, and GL's queries
are one class for each kind of query object.
Both fed user-written GLSL to the backends at runtime, which the move to
bytecode emitted straight from the shader generators leaves no compiler
for. The frontend's own shader pipeline covers post-processing.
The presentation pass keeps a plain copy and the built-in correction
shader for output resampling, colour space and gamma correction and HDR
scaling, now compiled in rather than loaded from Sys/Shaders. The
graphics-mod system keeps its draw, EFB, projection and texture actions;
custom pipelines, materials, shader, mesh and sampler assets, the custom
constant buffers in every backend and the two mods built on them are
gone, along with the shader generators' custom-shader hooks.
The whole ownership model was getting a bit of a mess, with a some
of special cases to deal with. And I'm planning to make it even more
complex in the future.
So here is some upfront work to convert it over to reference counted
pointers.
I think this is a relic of D3D9. D3D11 and D3D12 seem to work fine without it. Plus, ViewportCorrectionMatrix just didn't work correctly (at least with the viewports being generated by the new scissor code).

This stops the virtual method call from within the Renderer constructor.
The initialization here for GL had to be moved to VideoBackend, as the
Renderer constructor will not have been executed before the value is
required.
