[PATCH v1 11/51] perf vendor events intel: Refresh alderlake-n metrics

Sun Feb 19 01:28:08 PST 2023
Update the alderlake-n events from 1.16 to 1.18 (no change) and
metrics. Generation was done using https://github.com/intel/perfmon.
Notable changes are TMA metrics are updated to version 4.5, TMA info
metrics are renamed from their node name to be lower case and prefixed
by tma_info_, MetricThreshold expressions are added and the smi_cost
metric group is added replicating existing hard coded metrics in
stat-shadow.
