[var] Adjust API in prep for 'avar' implementation
...
The 'avar' table does not allow random access to axis maps,
so change API to avoid quadratic-time implementation.
Removed -hb_ot_var_normalize_axis_value(), added
+hb_ot_var_normalize_variations() and
+hb_ot_var_normalize_coords() instead.

[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.

The decomposition is very obscure and unlikely to help

Disable OTL processing for Hebrew if GPOS doesn't have Hebrew subtable
...
New approach to fix this:
69f9fbc420https://github.com/behdad/harfbuzz/issues/347#issuecomment-267838368
With U+05E9,U+05B8,U+05C1,U+05DC and Arial Unicode, we now (correctly) disable
GDEF and GPOS, so we get results very close to Uniscribe, but slightly different
since our fallback position logic is not exactly the same:
Before: [gid1166=3+991|gid1142=0+737|gid5798=0+1434]
After: [gid1166=3+991|gid1142=0@402,-26+0|gid5798=0+1434]
Uniscribe: [gid1166=3+991|gid1142=0@348,0+0|gid5798=0+1434]
