[Indic] Add Uniscribe bug feature for dotted circle
...
For dotted-circle independent clusters, Uniscribe does no Reph shaping
for the exact sequence Ra+Halant+25CC. Which also is the only possible
sequence with 25CC at the end.

This introduced a failure, which we tracked down to a test case like this:

The final character is a Ra that should be put in a syllable of it's
own. And we do. But it will interact with the Halant before it. So
now we finally are convinced that we have to limit features to syllable
boundaries. That's coming after lunch!
