Move Noto Sans Tai Le to the end of the font fallback list.

This is to make sure the East Asian punctuation shared between CJK languages
and Tai Le are rendered from the CJK fonts when no language is specified
for the text, or CJK text is rendered in a non-CJK locale.

Also remove the old comment about 64k glyphs limit.
