[subset-perf] Signficiantly speed up ClassDef*::subset.
Eliminates the usage of a glyph -> klass hash map and replaces it with a vector storing the mapping. This allows us to use the vector directly as the iterator driving the serialize. Approximately 1% speedup for Noto Nastaliq.

[ot-tags] Speed up hb_ot_tags_from_complex_language()
Part of https://github.com/harfbuzz/harfbuzz/issues/3591
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.
