This is a relatively minimal change to adjust all the gallium interfaces

PIPE_CAP_SM3 has always been an odd one out of all our caps. While most
other caps are fine-grained and single-purpose, this cap encode several
features in one. And since OpenGL cares more about single features, it'd
be nice to get rid of this one.
As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.
The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the
drivers, most of who doesn't care a whole lot about DX9 specifically.

One of the pains of implementing a gallium driver is filling in a million
pipe caps you don't know about yet when you're just starting out. One of
the pains of working on gallium is copy-and-pasting your new PIPE_CAP into
each driver. We can fix both of these by having each driver call into the
default helper from their default case, so that both sides can ignore each
other until they need to.
