[Indic] Disallow decomposition of a couple characters

This is a hack for now. Will be fixed when we do complex-shaper-driven
normalization properly.
The results with or without decomposition are the same, but Uniscribe
does not normalize, so this matches better.

[Indic] Accept a forced Rakar sequence at the end of syllable
...
In Sinhala, Rakar is formed by Al-Lakuna,ZWJ,Ra. If you put that at the
end of a Consonant,Matra syllable, you get a dotted-circle from
Uniscribe. Apparently adding a ZWJ before the Al-Lakuna "fixes" that.
And people have been encoding that sequence... So, allow a forced
"ZWJ,Virama,ZWJ,Ra" sequence at the of syllables.
Fixes some 100 or more of Sinhala failures. Now at 622 only (0.23%).
