[llvm-branch-commits] [BOLT][NFC] Simplify doTrace in BAT mode (PR #143233)

`BoltAddressTranslation::getFallthroughsInTrace` iterates over address
translation map entries and therefore has direct access to both original
and translated offsets. Return the translated offsets in fall-throughs
list to avoid duplicate address translation inside `doTrace`.
