Behdad Esfahbod 83353f13f4 [layout] Reduce memory use slightly

Behdad Esfahbod edec8946ed New API: hb_ot_layout_script_select_language2()
Variant that outputs chosen_language.

Not sure why the original API didn't have this. The script
counterpart has.

Combined with previous commit, this shows up to 12% speed up with
Roboto and the en-words (ie. short strings) benchmark, about 5%
for longer English tests, and no adverse effect on heavier fonts.

Behdad Esfahbod b96622d15c [layout] Use a cache for main input ClassDef of (Chain)ContextLookupFormat2
This commit adds a per-lookup caching infrastructure to GSUB/GPOS, and
uses it to cache input ClassDef.get_class value for (Chain)ContextLookupFormat2.

For fonts heavy on use of heave class-based2 context matching, this shows
a good speedup. For NotoNastaliqUrdu for example, I observe 17% speedup.

Unfortunately not many other lookups can use a cache like this :(.
