765c0b364d refactor: combine Chain::findFirstBlockWithTime/findFirstBlockWithTimeAndHeight (Antoine Riard)

Pull request description:

  As suggested in #14711, pass height to CChain::FindEarliestAtLeast to
  simplify Chain interface by combining findFirstBlockWithTime and
  findFirstBlockWithTimeAndHeight into one
