intel/perf: Get INTEL_PERF_QUERY_GUID_MDAPI metric id from sysfs
What does this MR do and why?
This changes are mostly aimed to make Xe KMD support MDAPI by reading INTEL_PERF_QUERY_GUID_MDAPI metric id from sysfs instead of query metrics and add a copy of INTEL_PERF_QUERY_GUID_MDAPI. But it also changes i915 behavior to match Xe KMD and drops a bunch of i915 code that is not needed with this approach.
