Embed hb_ot_shape_plan_t into hb_shape_plan_t
...
No other shaper will need shape_plan_data, by definition. So, remove
abstraction layer and always create hb_ot_shape_plan_t as part of
hb_shape_plan_t.

[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.
