Move this down into the D3D11 renderer. Achieve this by passing a
mutable pointer to the memory program cache to the ContextImpl.

This will allow the D3D11 back-end to more easily sync state then
apply state changes. It also cleans up the gl-side Context a bit.

This also changes the dirty TF object to use a Serial, which is more
secure for very edge-care reallocation issues. It also moves the
StateManager11::updateState call to be the very first thing that
happens in a draw call. This prepares the back-end for making the
state sync actually happen in Context11::syncState, instead of
inside the draw call.

Also moves a bit more TF management code out of RendererD3D and

Any time we would query ProgramD3D for a particular vertex or pixel
shader, we would iterate over all the cached shaders of the program
looking for the matching input or output layout signature. This change
makes it so we only compute the index of the matching shader once,
and subsequent calls will re-use the shader index. This should speed
up the draw call benchmarks.

Also include a fix to the Serial class that initializes a Serial value
to an invalid sentinel value. This ensures that comparing any other
Serial (including another invalid serial) to the invalid serial will
return not-equals.

extension name is supported, instead of having two variants
OVR_multiview and OVR_multiview2. We're only supporting the WebGL

GL_OVR_multiview2. Shader restrictions were also removed from the
