Message Filters: emit AyuGram-style <type>N</type> tag for regex matching

ForkRegexMessageFilters.matches(message:) now appends a trailing
<type>N</type> tag (approximating AyuGram Android's MessageObject.TYPE_*
constants) so patterns like <type>1</type> (photo) ported from AyuGram
Android continue to work here.
