[Indic] Move Halant with after-base consonants
...
Normally, we attach the Halant to the previous character and move it
with it. For after-base consonants however, the Halant "belongs" to the
consonant after, so attach it so.
This fixes Bengali sequences involving post-base consonant Ya, which
should ligate with the Halant to form Ya Phala, but previously a
reordered matras was blocking the ligation.

[Indic] Apply presentation-forms features all at once
...
Seems like this is what Uniscribe is doing, and does not break any fonts
we tested (with Devanagari, Malayalam, Khmer, and Bengali), while fixing
some Ra Phala sequences for Bengali with Vrinda. Fixes another 2% of
Bengali failures (a couple more to go).

[Indic] Disable 'kern' in Uniscribe bug compatibility mode
...
Uniscribe does not apply 'kern' in the Indic module. Some of the Khmer
fonts they ship have small adjustments in the 'kern' table. Disable
'kern' in the Indic module under Uniscribe bug compatibility mode.
Fixes some 10% of the Khmer failures. Remains under 3% (excluding
dotted-circle ones).
