mesa/st: Simplify st_choose_matching_format().

We now have a nice helper function for finding those memcpy formats,
without needing to go through each entry of the mesa format table to
see if it happens to match.

While looking at sysprof of a softpipe GLES2 CTS run, we were spending
~8% of the CPU on ChooseTextureFormat.  With this, roughly the same
region of the testsuite was .4%.

v2: Add Ken's fix for canonicalizing array formats.
