mesa: fix VIEWPORT_INDEX_PROVOKING_VERTEX and LAYER_PROVOKING_VERTEX queries

Browse source 
These are implementation-dependent queries, but so far we just returned the
value of whatever the current provoking vertex convention was set to, which
was clearly wrong.
Just make this a variable in the context constants like for other things
which are implementation dependent (I assume all drivers will want to set
this to the same value for both queries), and set it to GL_UNDEFINED_VERTEX
which is correct for everybody (and drivers can override it).
