perf vendor events intel: Update tigerlake 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:

 - tma_info_bottleneck* metrics, an abstraction or summarization of
   the 100+ TMA tree nodes into 12-entry familiar performance metrics.
 - Reduce number of events (multiplexing) for tma_info_system_gflops,
   tma_info_core_flopc, tma_info_inst_mix_ipflop and tma_ports_utilized_0.
 - Fixes for tma_info_bottleneck_mispredictions and
   tma_info_bad_spec_branch_misprediction_cost.
 - New tma_info_inst_mix_ippause metric.
 - tma_serializing_operation is raised to level 3.
 - Swapped tma_info_core_ilp (becomes per SMT thread) and
   tma_info_pipeline_execute (per physical core).
 - tma_nop_instructions and tma_shuffles_256b are lowered to level 4
   under tma_other_light_ops_group.
 - Reduced number of events when SMT is off.
 - Tuned thresholds for tma_info_bottleneck_branching_overhead,
   tma_fetch_bandwidth and tma_ports_utilized_3m.

The update came from:
