[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.

[aat] Remove deleted-glyhs after applying kerx/kern
...
Finally: Fixes https://github.com/harfbuzz/harfbuzz/issues/1356
Test case:
$ ./hb-shape GeezaPro.ttc -u U+0628,U+064A,U+064E,U+0651,U+0629
[u0629.final.tehMarbuta=4+713|u064e_u0651.shaddaFatha=1@0,-200+0|u064a.medial.yeh=1+656|u0628.initial.beh=0+656]
The mark positioning (kern table CrossStream kerning) only works if deleted
glyph (as result of ligation) is still in stream and pushed through the
state machine.
