Merge #17004: validation: Remove REJECT code from CValidationState

a1a07cfe99 [validation] Fix peer punishment for bad blocks (John Newbery)

Pull request description:

  We no longer send BIP 61 REJECT messages, so there's no need to set
  a REJECT code in the CValidationState object.

  Note that there is a minor bug fix in p2p behaviour here. Because the
  call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
  previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
  then there are cases were `MaybePunishNode()` can get called where it
  wasn't previously:

  - when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
  - when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.

  Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
  only internal reject code was `REJECT_HIGHFEE`, which was only set in
  ATMP.

  This reverts a minor bug introduced in 5d08c9c579.
