  [BOLT][NFCI] Skip validation in parseLBRSample (#143288)

Parsed branches and fall-throughs are validated in `doBranch` and
`doTrace` respectively. Simplify parseLBRSample by omitting the
validation. This also speeds up perf data processing as checks are only
done once for aggregated branches/fall-throughs and not individual LBR
entries.

Since invalid/external addresses are no longer sanitized during parsing,
sanitize them in `doBranch`.

Test Plan: updated X86/pre-aggregated-perf.test
