  [BOLT] Add perf2bolt pre-aggregated profile output

Add a pre-aggregated profile output format (`--profile-format=preagg`)
so perf.data can be pre-parsed/aggregated and used as input with -pa.

Supports branch (T traces) and basic samples (S records).

Currently only covers main binary, can be extended to cover multi-DSO.

Test Plan: Updated perf_test.test, added perf_brstack.test
