perf vendor events intel: Update skylake 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.
     - 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.
