anv: Disallow fast-clears which require format-reinterpretation

In order to actually hit this case you have to be using a very odd
color/view combination.  The common cases of clear-to-zero and 0/1 clear
colors with an sRGB view don't require any re-interpretation.  This is
probably better than always resolving whenever we have a format mismatch
like we are today because that hits the sRGB case every time.
