Behdad Esfahbod df32eaae42 [indic] Disallow vowel mark combinations that spoof other vowel marks 
Fixes https://github.com/harfbuzz/harfbuzz/issues/1019

Devanagari regressed because Uniscribe doesn't enforce the full set.

Tests added with the *-vowel-letters.txt files in tree and Noto fonts.

Behdad Esfahbod 5143654716 [khmer] Rewrite grammar completely

Failures down from 44 to 35:

KHMER: 299089 out of 299124 tests passed. 35 failed (0.0117008%)

We still don't enforce the one-matra rule pre-decomposition, but enforce
an order and one-matra-per-position post-decomposition.
