interfaces: convert the repository zope interfaces to Protocol classes
This is the same transformation as
382d9629cede did for dirstate. The same
caveat applies- the code may not be valid, since the functions are missing the
`self` arg, and the attrs should be plain attrs, not zope `Attribute`. These
classes are pretty intertwined however, so making the same transformation to
everything makes it easier to change and review.
Additionally, there are some classes that subclass multiple protocol classes,
and should themselves subclass `typing.Protocol` to be a protocol class. But
defer that for now for clarity.
