This is a backport of core#21575 [4/6]
https://github.com/bitcoin/bitcoin/pull/21575/commits/fa0c7d9ad24d3c9515d3f9c136af4071cbd79055
Notes:
- we don't have the ReadRawBlockFromDisk functions, which are related to segwit
- some functions were in blockdb.{h|cpp} rather than validation.{h|cpp} in Bitcoin ABC. blockdb.{h|cpp} will most likely be unnecessary and deleted as a result of this series of backports.
