dirstate: move code paths for backup from dirstateguard to dirstate

This can centralize the logic to write in-memory changes out correctly
according to transaction activity into dirstate.

Passing 'repo' object to newly added functions is needed to examine
current transaction activity in subsequent patches, because 'dirstate'
itself doesn't have direct reference to it.
