swrast: use STATIC_ASSERT to make sure texfetch table isn't missing entries

When new MESA_FORMAT_x enums are added we need to add a new entry in
the table of texture fetch functions.  In the past this has been
missed if swrast isn't actually tested.  Using a static assertion
should help with that.
