Merge #16226: Move ismine to the wallet module

e61de6306f Change ismine to take a CWallet instead of CKeyStore (Andrew Chow)
7c611e2000 Move ismine to wallet module (Andrew Chow)

Pull request description:

  `IsMine` isn't used outside of the wallet except for the tests. It also doesn't make sense to be outside of the wallet. This PR moves `IsMine` into the wallet module and for it to take a `CWallet` instead of `CKeyStore`. The test that used `IsMine` is also moved to the wallet tests.

  This is first [prerequisites](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes#ismine) for the wallet structure changes.

ACKs for commit e61de6:
  MarcoFalke:
    re-ACK e61de6306f (only change is rebase with git auto-merge)
  meshcollider:
    Very light code review ACK e61de6306f
