Sync the Linux kernel perf PMU event json with the latest upstream
Intel perfmon repository. The updates were created by running:
https://github.com/intel/perfmon/blob/main/scripts/create_perf_json.py

v2 adds fixes for a number of umask encodings a bug caught by Sashiko
in v1. The fix to the perfmon converter script is in:
ttps://github.com/intel/perfmon/pull/388

v1:
https://lore.kernel.org/linux-perf-users/20260924053645.3555041-1-irogers@google.com/

The updated events were published in:

  https://github.com/intel/perfmon/commit/8732d043b432e9d04086a07feb23d9df70a10f17

Fix wrong encoding of UMaskExt.

Fixes: 917f63ad7580 ("perf vendor events: Update graniterapids events and add counter information")
