[ot-tags] Speed up hb_ot_tags_from_language()
Part of https://github.com/harfbuzz/harfbuzz/issues/3591
"After that, bulk of the time I suppose is spent in binary-searching the
language table. I suggest we split the language table in 2-letter and
3-letter tags, to speed-up the vast majority of cases that are
2-letter."

2. All the subtag_matches outside the switch match long strings (>= 6 or so).
As such, check the tag for such length before going into any of them.
