Part of https://github.com/harfbuzz/harfbuzz/issues/1652

Sorry for the noise, downstream custom builders.  Please adjust.

Fixes https://github.com/harfbuzz/harfbuzz/pull/660

Also see https://github.com/roozbehp/unicode-data/issues/6

Test added, using NotoSansCham built from Noto Phase III sources.

With javatext.ttf, the reodering medial Ra gets its advance width
zero'ed in Uniscribe implementation, and the font adds the advance
back.  Our Indic shaper does not do that, but USE does.  So, route
Javanese through USE.  That's what Microsoft does anyway.  Test:

  U+A9A5,U+A9BA

This also seems to fix the following sequence, and variations thereof:

  U+A99F,U+A9C0,U+A9A2,U+A9BF

Test stats remain unchanged, except for Malayalam, which we investigate:

Though, looks like gcc was smart enough to produce the same code
before...

Touch code just enough to preserve previous syllable structure
and functionality as closely as possible.  Many further cleanups
coming later.

No output change.

We don't need Indic table for those.

-#define indic_offset_total 4416
+#define indic_offset_total 3816

-}; /* Table occupancy: 60% */
+}; /* Table occupancy: 69% */

No functional change.

Handles Tai Tham, Cham, and New Tai Lue for now.

Not hooked up yet.

Nothing functional in there yet.

So far, we're parsing IndicSyllabicCategory.txt and IndicMatraCategory.txt
fils from Unicode Character Database and store them in an array to be used
by the shaper.  Also hooked up the shaper, but it does not do anything
right now.
