gallium: Add a transcode_astc driconf option

Browse Source 
This is similar to the transcode_etc flag in that it changes the ASTC
fallback (when present) to use DXT5 instead of RGBA8888.  This reduces
the memory footprint of the app at the expense of a bit of correctness.
Because it's not quite correct, it's hidden behind a driconf option.
