mesa/formatquery: Added boilerplate code to extend GetInternalformativ

The goal is to extend the GetInternalformativ query to implement the
ARB_internalformat_query2 specification, keeping the behaviour defined
by the ARB_internalformat_query if ARB_internalformat_query2 is not
supported.

v2: Don't require ARB_internalformat_query when profile is GLES3.
