Driver queries are organized as a single hierarchy where queries are
categorized into groups. Each goup has a list of queries and a maximum
number of queries that can be sampled. The list of available groups can
be obtained using pipe_screen::get_driver_query_group_info.
This will be used by GL_AMD_performance monitor.
