df5a50e5de bench/blockencodings: add compact block reconstruction benchmark (Anthony Towns)
Pull request description:
Reconstructing compact blocks is on the hot path for block relay, so revert changes from #28391 and #29752 that made it slower. Also add a benchmark to validate reconstruction performance, and a comment giving some background as to the approach.
