mesa: Add QueryInternalFormat to device driver virtual table

This new function queries different driver parameters for a particular target
and texture format. It is basically a driver hook to support
ARB_internalformat_query2.

Since ARB_internalformat_query2 introduced several new query parameters
over ARB_internalformat_query, having one driver hook for each parameter
is no longer feasible. So this is the generic entry-point for calls
to glGetInternalFormativ and glGetInternalFormati64v.
