filemerge: return whether the file is deleted for nomerge internal tools

We're going to support the filemerge code resolving change/delete conflicts in
upcoming patches. Some of these resolutions require that the dirstate be
modified. Modifying the dirstate directly from in here would be (a) a pretty
bad layering violation and (b) wrong because all dirstate removals should
happen before adds. So in this and upcoming patches we're instead going to pass
whether the file is deleted up to merge.mergestate, then in there figure out
what dirstate action needs to be taken.
