mesa/formats: Autogenerate the format_info structure from a CSV file

Instead of a having all of the format metadata in a gigantic hard-to-edit
array of type struct format_info, we now have a human-readable CSV file.
The CSV file also contains more format information than the format_info
struct contained so we can potentially make format_info more detailed later.

The python to generate the format information was added the previous
commit.  This commit turns it on in both automake and scons builds.

v2: Split into two commits and stuff to generate format_info.c from scons
