Here we add the notion of prunable tables for the `TruncateTail` operation in the freezer. TruncateTail for the chain freezer now only truncates the body and receipts tables, leaving headers and hashes as-is. This change also requires changing the validation/repair at startup to allow for tables with different tail. For the header and hash tables, we now require them to start at number zero. --------- Co-authored-by: Felix Lange <fjl@twurst.com> Co-authored-by: Gary Rong <garyrong0905@gmail.com>
