Subject: perf vendor events: Update Intel broadwell
Git-commit: eb4f8d7787f115a724e4ffcb8d1d659249b04f9b
Patch-mainline: v6.1-rc1
References: SLE15-SP5 - update json files

Events remain at v26, and the metrics are based on TMA 4.4 full.

Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf

Updates include:
 - Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
 - _SMT suffix metrics are dropped as the #SMT_On and #EBS_Mode are
   correctly expanded in the single main metric.
 - Addition of all 6 levels of TMA metrics. Child metrics are placed
   in a group named after their parent allowing children of a metric
   to be easily measured using the metric name with a _group suffix.
 - ## and ##? operators are correctly expanded.
 - The locate-with column is added to the long description describing
   a sampling event.
 - Metrics are written in terms of other metrics to reduce the
   expression size and increase readability.

Tested with 'perf test':
 10: PMU events                                                      :

 10.2: PMU event map aliases                                         : Ok
 10.3: Parsing of PMU event table metrics                            : Ok
 10.4: Parsing of PMU event table metrics with fake PMUs             : Ok
