[morx/kerx] Limit range to subtable when sanitizing

[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.

family of three, then makes family of four out of that and the last
