[Indic] Relax grammar
Now that we insert dotted-circle, tests break more easily when our indic
machine breaks.
In particular, a few Devanagari tests were having sequences like
"C,H,ZWJ,N", and because of the ZWJ the Nukta does NOT get reordered to
before the Halant as the grammar used to expect... Fixup.
Another case is as simple as "C,ZWJ,SM".
Fixes 10 out of 79 failures:

[Indic] Fix Khmer syllable-final coeng-consonant
Brings down Khmer failures from 162 to 47.
KHMER: 299077 out of 299124 tests passed. 47 failed (0.0157125%)
Also rebaselined some of the test files that had only-inherited lines.
Removing those, the stats are:

addressed.

Fixup test failure reporting
After we implemented dotted-circle, we were still ignoring any tests
that had dottedcircle in it for any of the shapers. That meant that if
we wrongly outputted dottedcircle, the test was being ignored. Ouch!
Fixing that shows regressions across the board. Most are Uniscribe
bugs: NOT inserting dotted-circle when it should. Some are arou
machine bugs. This is in fact a nice way to catch Indic-machine
deficiencies and when I fix the regressions, our clusters should be
much closer to Uniscribe. For now, we regressed from:
