diff: use promisor-remote.h instead of fetch-object.h

The repository_format_partial_clone global and fetch_objects()
should not be used anymore when there can be more than one
promisor remote. Instead let's use has_promisor_remote()
and promisor_remote_get_direct() from "promisor-remote.h".

This way all the configured promisor remotes will be taken
into account, not only the one specified by
extensions.partialClone.
