Plumbing to get shape plan and font into complex decompose function
So we can handle Sinhala split matras smartly... Coming soon.

[Indic] Decompose Sinhala split matras the way old HarfBuzz / Pango did
Had to do some refactoring to make this happen...
Under uniscribe bug compatibility mode, we still plit them
Uniscrie-style, but Jonathan and I convinced ourselves that there is no
harm doing this the Unicode way. This change makes that happen, and
unbreaks free Sinhala fonts.

[Indic] Implement dotted-circle insertion for broken clusters
No panic, we reeally insert dotted circle when it's absolutely broken.
Fixes most of the dotted-circle cases against Uniscribe. (for Devanagari
fixes 80% of them, for Khmer 70%; the rest look like Uniscribe being
really bogus...)
I had to make a decision. Apparently Uniscribe adds one dotted circle
to each broken character. I tried that, but that goes wrong easily with
split matras. So I made it add only one dotted circle to an entire
broken syllable tail. As in: "if there was a dotted circle here, this
would have formed a correct cluster." That works better for split
stuff, and I like it more.

[OT] Slightly adjust normalizer
The change is very subtle. If we have a single-char cluster that
decomposes to three or more characters, then try recomposition, in
case the farther mark may compose with the base.

[OT] Avoid calling get_glyph() twice
Essentially move the glyph mapping to normalization process.
The effect on Devanagari is small (but observable). Should be more
observable in simple text, like ASCII.
