lib: Improve notmuch_database_{add,remove}_message documentation.

State up front that these functions may add a filename to an existing
message or remove only a filename (and not the message), respectively.
Previously, this key information was buried in return value
documentation or in "notes", which made it seem secondary to these
functions' semantics.
