perf/x86/intel: Fix the FRONTEND encoding on GNR and MTL
When counting a FRONTEND event, the MSR_PEBS_FRONTEND is not correctly
set on GNR and MTL p-core.
The umask value for the FRONTEND events is changed on GNR and MTL. The
new umask is missing in the extra_regs[] table.
Add a dedicated intel_gnr_extra_regs[] for GNR and MTL p-core.
Fixes: bc4000fdb009 ("perf/x86/intel: Add Granite Rapids")
