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.

[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 :(.

For BASE table format 1.1, the handling of design
space vs user space coordinates was inconsistent.
We were applying design -> user transformation
twice for the deltas, leading to wrong baseline
values.
