e0f66c1fbf GLRasterizer: Implemented instanced vertex arrays. 
Before each draw call, for every enabled vertex array configured as instanced, we take the current instance id and divide it by its configured divisor, then we multiply that by the corresponding stride and increment the start address by the resulting amount. This way we can simulate the vertex array being incremented once per instance without actually using OpenGL's instancing functions.

c5284efd4f Rasterizer: Implemented instanced rendering. 
We keep track of the current instance and update an uniform in the shaders to let them know which instance they are.

Instanced vertex arrays are not yet implemented.

ce722e317b gl_rasterizer: Use the streaming buffer itself for the constant buffer. 
Don't emut copies, especially not for data, which is used once. They just end in a huge GPU overhead.

28e90fa0e0 gl_rasterizer: Silence implicit truncation warning in SetupShaders() 
Previously this would warn of truncating a std::size_t to a u32. This is
safe because we'll obviously never have more than UINT32_MAX amount of
uniform buffers.

0f2ac928f2 video_core: Make global EmuWindow instance part of the base renderer class 
Makes the global a member of the RendererBase class. We also change this
to be a reference. Passing any form of null pointer to these functions
is incorrect entirely, especially given the code itself assumes that the
pointer would always be in a valid state.

This also makes it easier to follow the lifecycle of instances being
used, as we explicitly interact the renderer with the rasterizer, rather
than it just operating on a global pointer.

3a4841e403 core: Don't construct instance of Core::System, just to access its live instance 
This would result in a lot of allocations and related object
construction, just to toss it all away immediately after the call.

These are definitely not intentional, and it was intended that all of
these should have been accessing the static function GetInstance()
through the name itself, not constructed instances.

b37354cca8 GPU: Always enable the depth write when clearing the depth buffer. 
The GPU ignores that register when clearing, but OpenGL obeys the glDepthMask parameter, so we set the depth mask to GL_TRUE when clearing the depth buffer. It will be restored to the correct value automatically on the next draw call.
