[Indic] Position final subjoined consonants (and vowels) after matras
...
In Khmer, a final subjoined consonant or independent vowel can occur
after matras. This final subjoined thing should NOT be reordered to
before the matra even though it's subjoined.
Fixes another 1k of the Khmer failures. Not much left really.

[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.

Seems like this is what Uniscribe is doing, and does not break any fonts

some Ra Phala sequences for Bengali with Vrinda. Fixes another 2% of
Bengali failures (a couple more to go).

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).
