vc4: Enable MSAA.

Browse Source 
We still have several failures in the newly enabled tests in simulation:
sRGB downsampling is done as if it was just linear, stencil blits are not
supported on MSAA either, and derivatives are still not supported
(breaking some MSAA simulation shaders).  So, other than sRGB downsampling
quality, things seem to be in good shape.
