[Indic] Add test for matra group
...
The spec says: "[{M}+[N]+[H]]", and that's what Uniscribe implements.
We instead do: "{M+[N]+[H]}", which means we allow Nukta and Halant
after all Matras, not just the last one. It makes more sense.

[Indic] Reorder Reph to before the Halant after Matras
...
Uniscribe doesn't do it, but we want to do as it gives the Reph the
opportunity to interact with the Matras. Test with mangal for example.
Sequence: <0930,094d,0915,094b,094d>
In test suite already.

[Indic] Don't clear the mask for Reph
...
This was removing the mandatory global 1 bit in the mask and hence
disabling GPOS for Reph!

[Indic] Add tricky reordering test cases
...
In the case of Consonant,LeftMatra,Halant, Uniscribe leaves the Halant
where it is, but we want to move it with the Matra as that makes more
logical sense.

[Indic] Do Reph repositioning in final reordering like the spec says
...
This introduced a failure, which we tracked down to a test case like this:
U+092E,U+094B,U+094D,U+0930
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!

U+0985 BENGALI LETTER A followed by U+09D7 BENGALI AU LENGTH MARK.
According to Bobby de Vos on the mailing list, this results in a dotted
circle with most shaping engines, but is a legitimate sequence in this
minority language.
We reached the consensus on the list to NOT implement dotted-circle
in HarfBuzz.
