perf/x86/intel: Fix the FRONTEND encoding on GNR and MTL

Browse source

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.
