r300g: enable MSAA on r300-r400, be careful about using color compression

MSAA was tested by one user on RS690 and it works for him with color
compression (CMASK) disabled. Our theory is that his chipset lacks CMASK RAM.

Since we don't have hardware documentation about which chipsets actually have
CMASK RAM, I had to take a guess based on the presence of HiZ.
