emacs: create notmuch-tag.el, and move appropriate functions from notmuch.el

Tagging functions are used in notmuch.el, notmuch-show.el, and
notmuch-message.el.  There are enough common functions for tagging
that it makes sense to put them all in their own library.

No code is modified, just moved around.
