gallium: add new fields to pipe_driver_query_info

According to the spec of GL_AMD_performance_monitor, valid type values
returned are UNSIGNED_INT, UNSIGNED_INT64_AMD, PERCENTAGE_AMD, FLOAT.
This also introduces the new field group_id in order to categorize
queries into groups.

v2: add PIPE_DRIVER_QUERY_TYPE_BYTES

v3: fix incorrect query type for radeon and svga drivers
