virgl: fix format conversion for recent gallium changes.

virgl: fix format conversion for recent gallium changes.

The virgl formats are fixed in time snapshots of the gallium ones,
we just need to provide a translation table between them when
we enter the hardware.

This fixes a regression since Eric renumbered the gallium table.

Fixes: c45c33a5a2 (gallium: Remove manual defining of PIPE_FORMAT enum values.)

v1 by Dave Airlie <airlied@redhat.com>
v2: virgl: Add a number of formats to the table that are used, e.g. for vertex
    attributes
v3: cover some more missing formats from a piglit run
