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. Reviewed-by: Dave Airlie <airlied@redhat.com>
