mesa: Add Mesa ARB_get_program_binary helper functions

V2 (Timothy Arceri):
 - add extra code comment
 - stop passing around void *binary and just pass
   program_binary_header *hdr instead.
 - move to src/mesa/main rather than src/util

V3 (Timothy Arceri):
 - Move more code out of the backend and into the common
   helpers.
