Move FindForkInGlobalIndex from BlockManager to CChainState

The helper was moved in commit b026e318c39f59a06e29f1b25c7f577e01b25ccb,
which also mentioned that it could be moved to CChainState. So do that,
as the functionality is not block-storage related.

This also allows to drop one function argument.
