Do not allow recursiving to same position and same lookup
...
This is just to make it harder to be extremely slow. There definitely
are ways still, just harder. Oh well... how do we tame this problem
without solving halting problem?!

Implement SYRIAC ABBREVIATION MARK with 'stch' feature

The feature is enabled for any character in the Arabic shaper.
We should experiment with using it for Arabic subtending marks.
Though, that has a directionality problem as well, since those
are used with digits...

Normalize various spaces to space if font doesn't support

This resurrects the space fallback feature, after I disabled
the compatibility decomposition. Now I can release HarfBuzz
again without breaking Pango!
It also remembers which space character it was, such that later
on we can approximate the width of this particular space
character. That part is not implemented yet.
We normalize all GC=Zs chars except for U+1680 OGHA SPACE MARK,
which is better left alone.

Relax inert checks

Previously, when creating an object from inert inputs (eg:

empty object. This is not helpful as there are legitimate
usecases to do that.
We now never return the inert object unless allocation failed.
Tests are revised to reflect.
