i965: Add support for ARGB2101010 rendering.

GL 3.0 specifies GL_RGB10_A2 as a required sized format for rendering
and texturing.

This introduces two piglit regressions: one due to fbo-mipmap-copypix
hitting swrast GetRow (we want to convert swrast to MapRenderbuffer),
and one due to fbo-blending-formats being too picky while leaving
dithering on.
