Behdad Esfahbod 044d7a06db [indic-like] Add per-lookup per-syllable flag

In fact, removes the clear-syllables call completely.

[ot] Keep substituted Default_Ignorables (#2886)
Don’t replace Default_Ignorables with zero-width space if they are
substituted or multiplied, not just when ligated.

After this change, HarfBuzz output matches that of Uniscribe and
CoreText for the new tests.

Fix djgpp complains by tweaking templates (#1579)
For some reasons djgpp doesn't understand "unsigned int" can be same
with one of uint*_t anyway so lets do that for it explicitly.

Just to note, our CI's djgpp is based GCC 7.2.0 and isn't old.

Behdad Esfahbod 748962264a [aat] Disable mark advance zeroing if kern table has state-machines
Geeza Pro for example, relies on that for fancy mark positioning.

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 ca23567f41 Disable fallback mark positioning if kern table has cross-stream kerning
