perf vendor events intel: Update haswell TMA metrics to 4.7 

Top-Down Microarchitecture Analysis (TMA) metrics simplify
cycle-accounting using microarchitecture-abstracted metrics
organized in one hierarchy. This update is from version 4.5 to
4.7.

The update includes:

 - Swapped tma_info_core_ilp (becomes per SMT thread) and
   tma_info_pipeline_execute (per physical core).
 - Tuned thresholds for tma_fetch_bandwidth and
   tma_ports_utilized_3m.

The update came from:

https://github.com/intel/perfmon/pull/140
https://github.com/intel/perfmon/pull/138

"PublicDescription": "This metric serves as an approximation of legacy x87 usage. It accounts for instructions beyond X87 FP arithmetic operations; hence may be used as a thermometer to avoid X87 high usage and preferably upgrade to modern ISA. See Tip under Tuning Hint.",
"ScaleUnit": "100%"
