Behdad Esfahbod 385f78b312 [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.

Behdad Esfahbod 9c04b60583 [kern] In Format1, adjust how kerning is done
In a series of kerns in one action, kern all but last glyph forward,
and the last one backward.  Seems to better match what CoreText is doing.

Test cases, with GeezaPro Arabic:

$ ./hb-shape GeezaPro_10_10.ttc -u U+0631,U+0628
[u0628.beh=1+1415|u0631.reh=0@-202,0+700]

$ ./hb-shape GeezaPro_10_10.ttc -u U+0628,U+064F
[u064f.damma=0@0,-250+-250|u0628.beh=0@250,0+1665]

In a later change, I'll make kern machine avoid producing negative kerns.
