panfrost: Add a blendable format table

Browse Source 
Map PIPE formats that are fixed-function blendable to their (internal,
writeback) tuple. Formats which are renderable but require a blend
shadeer will be handled elsewhere to keep this easy to verify.

Notice the subset of SFBD and MFBD color writeback formats used to
identify fixed-function blendable formats are bit compatible, so it
suffices to store only the MFBD variants.
