manifest: remove manifest.add and add memmfctx.write
This removes one more dependency on the manifest class by moving the write
functionality onto the memmanifestctx classes and changing the one consumer to
use the new API.
By moving the write path to a manifestctx, we now give the individual manifests
control over how they're read and serialized. This will be useful in developing
new manifest formats and storage systems.
