[aat] Consume glyph insertion from buffer's max_ops (#2223) 
Glyph insertion is an expensive operation and we like to have it limited
based on buffer's input size which is handled by buffer's max_ops.

 After the change: 0.02s user 0.00s system 98% cpu 0.024 total

Which takes much longer on valgrind and tsan bots.

a371a28cda [AAT] Use a ring buffer for ligature stack 
I think Apple does very similarly, but probably with a stack size of 16.
We do it with a stack size that is currently set to 64.

ae8ed58a6e [aat.morx] Remove set_object() business 
With OS X 10.13 Apple Chancery fails to ligate if we limit each morx
sub-chain to its declared length.  Perhaps their newer compiler does
object-sharing across sub-chains.  Anyway, since that's a valid, if
unspecified, way to compile tables, remove enforcement.

Probably do the same with kern/kerx.
