Add perf2bolt `--heatmap` option to produce heatmaps during profile aggregation. Distinguish exclusive mode (`llvm-bolt-heatmap`) and optional mode (`perf2bolt --heatmap`), which impacts perf.data handling: exclusive mode covers all addresses, whereas optional mode consumes attached profile only covering function addresses. Test Plan: updated per2bolt tests: - pre-aggregated-perf.test: pre-aggregated data, - bolt-address-translation-yaml.test: pre-aggregated + BOLTed input, - perf_test.test: no-LBR perf data.
