Subject: [PATCH] [USE] Remove non-canonical decompositions

We have had added this in Indic shaper to assist shaping these scripts.
In Universal Shaping Engine however, it is up to font designer to
decompose them.  Hence moving them from Indic shaper to USE was
wrong.

Fixup for f6ba63b2e8eb577385f70758efdd3b8408c8a9cb

Part of fixing https://github.com/behdad/harfbuzz/issues/387
