manifest: move treeinmem onto manifestlog

A previous patched moved all the serialization related options onto
manifestrevlog (since it is responsible for serialization). Let's move the
treeinmem option on manifestlog, since it is responsible for materialization
decisions. This reduces the number of dependencies manifestlog has on the old
manifest type as well, so we can eventually make them completely independent of
each other.
