treemanifest: separate flags for trees in memory and trees on disk

When we start writing tree manifests with one manifest revlog per
directory, it will still be nice to be able to run tests using tree
manifests in memory but writing to a flat manifest to a single
revlog. Let's break the current '_usetreemanifest' flag on the revlog
into '_treeinmem' and '_treeondisk'. Both are populated from the same
config, but after this change, one can temporarily hard-code
_treeinmem=True to see that tests still pass.
