[subset-cff] Compact parsed strings if using accelerator
Saves 32% on SourceHanSans/10000 benchmark!
Also, use memcmp now for writing out strings since now that our
ops are not super short, that's faster.
This makes cff-japanese test takes super long though; that needs
inspection.

[subset] don't copy the entire global/loca subr lists from the accelerator.
Instead run a closure on the retained charstrings and copy only the referenced subrs. This significantly speeds up cases with small character sets.
