merge-tree: add a new --quiet flag
Git Forges may be interested in whether two branches can be merged while
not being interested in what the resulting merge tree is nor which files
conflicted. For such cases, add a new --quiet flag which
will make use of the new mergeability_only flag added to merge-ort in
the previous commit. This option allows the merge machinery to, in the
outer layer of the merge:
* exit early when a conflict is detected
* avoid writing (most) merged blobs/trees to the object store
