This makes dvcfs/repofs much easier to work with and allows it to support isabs/abspath/etc correctly, as previously any full path (with root_marker "") would be impossible to distinguish from a relative one. This also detaches external workspaces from the main repo workspace in DvcFileSystem, which was necessary to be able to distinguish dvcfs abspaths from local external output paths. Note that currently we still have limited support for those (e.g. get/api supports them, but import doesn't) and this change keeps it that way.
