Move some interfaces to kopia package (#3500)

Searching for new bases is mostly kopia-specific but is going to require the store interface. With the way packages and interfaces are currently laid out it makes it impossible to easily get the interface added to the inject package without a cycle.

This moves functions that the kopia package provides into a subpackage of the kopia package that other things can then import

This change only moves code. No logic is updated
