mesa: Add texel fetch functions for BPTC-compressed textures
Adds functions to fetch from any of the four BPTC-compressed formats.
v2: Set the alpha component to 1.0 when fetching from the half-float formats
instead of leaving it uninitialised. Don't linearize the alpha component
when fetching from sRGB.
