[aat] Tweak fallback positioning logic when applying morx
...
Such that for Indic-like scripts (eg. Khmer), we don't do any fallback mark
advance-zeroing / positioning, but we do for Latin, etc. Reuses preferences
of our script-specific OpenType shapers for those.
Fixes regression: https://github.com/harfbuzz/harfbuzz/issues/1393
Which means, fixes again: https://github.com/harfbuzz/harfbuzz/issues/1264

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.

Happens even if the cross-stream kerning is for cursive attachment only. Oh well..
