  [BOLT][NFCI] Simplify DataAggregator using traces (#143289)

Consistently apply traces as defined in #127125 for branch profile
aggregation. This combines branches and fall-through records into one.

With large input binaries/profiles, the speed up in aggregation time
(`-time-aggr`, wall time):
- perf.data, pre-BOLT input: 154.5528s -> 144.0767s
- pre-aggregated data, pre-BOLT input: 15.1026s -> 9.0711s
- pre-aggregated data, BOLTed input: 15.4871s -> 10.0077s

Test Plan: NFC
