perf vendor events intel: Update rocketlake 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.
