merge-tree: support including merge messages in output
When running `git merge-tree --write-tree`, we previously would only
return an exit status reflecting the cleanness of a merge, and print out
the toplevel tree of the resulting merge. Merges also have
informational messages, such as:
* "Auto-merging <PATH>"
* "CONFLICT (content): ..."
* "CONFLICT (file/directory)"
* etc.
In fact, when non-content conflicts occur (such as file/directory,
modify/delete, add/add with differing modes, rename/rename (1to2),
etc.), these informational messages may be the only notification the
user gets since these conflicts are not representable in the contents
of the file.
Add a --[no-]messages option so that callers can request these messages
be included at the end of the output. Include such messages by default
when there are conflicts, and omit them by default when the merge is
clean.
