query: add completions for notmuch search-terms

Add completions to :query for the notmuch search terms. Most search
terms that seemed valid for interactive use in aerc are listed as
options. Some of them (from, to, tag, path, and folder) get actual
completions. The function was designed, so later patches can reuse it to
add completions to :cf, :filter and :search for notmuch accounts.
