freedreno/a3xx: unify vertex/texture formats into a single table

The table contains all the relevant information about each format. The
helper functions now just do lookups in the table.

Note that this adds support for a lot of formats that were previously
unsupported. Additionally it adds disabled support for integer render
buffers, which will require more work to actually enable.
