A "dance" is required with this uAPI, first we need to ask KMD what is the size of the giving query id, then memory needs to be allocated to match that size and then query again with the memory address set and at this time Xe KMD will copy the query data to memory. This dance was being duplicated in xe_engine_get_info() and anv_xe_physical_device_get_parameters() and the next patch will also use it in Iris, so here adding it common/xe and re-using as much as possible. There is one more implementation of this function in intel/dev but due to how libs are linked intel/dev can't depend on to intel/common.
