Merge #15452: Replace CScriptID and CKeyID in CTxDestination with dedicated types

78e407ad0c26190a22de1bc8ed900164a44a36c3 GetKeyBirthTimes should return key ids, not destinations (Gregory Sanders)
70946e7fee54323ce6a5ea8aeb377e2c7c790bc6 Replace CScriptID and CKeyID in CTxDestination with dedicated types (Gregory Sanders)

Pull request description:

  The current usage seems to be an overloading of meanings. `CScriptID` is used in the wallet as a lookup key, as well as a destination, and `CKeyID` likewise. Instead, have all destinations be dedicated types.

  New types:
  `CScriptID`->`ScriptHash`
  `CKeyID`->`PKHash`

ACKs for commit 78e407:
