Core Text seems to apply them to Latin text, but Uniscribe doesn’t.

It makes sense to disable this code these if editing is not needed.
However, this is also necessary to correctly display emoji sequences
in right-to-left direction.  For that reason, don't auto-disable it.

Add a flag to hb_buffer_t to prevent the insertion of dotted circles on incorrect character sequences. 

Current behavior unchanged if this flag is not set (and it isn't by default).

Adjust tests.

Fixes https://github.com/harfbuzz/harfbuzz/issues/1532

The override_features is used to override features that are normally
discretionary features, but in a specific shaper are for various
reasons desired to be bolted on or off, because they've been used
for inherent shaping.  As such, it makes sense that they also
override user features.  Ie. if user turned 'liga' on, we don't
want Khmer shaping to become broken...  Or turn 'clig' off...

Geeza Pro for example, relies on that for fancy mark positioning.

Fixes https://github.com/harfbuzz/harfbuzz/issues/1405

Cross-kerning can only take care of positioning vertically.  It doesn't
adjust mark advance...

Such that for Indic-like scripts (eg. Khmer), we don't do any fallback mark
advance-zeroing / positioning, but we do for Latin, etc.  Reuses preferences
of our script-specific OpenType shapers for those.

Fixes regression: https://github.com/harfbuzz/harfbuzz/issues/1393
Which means, fixes again: https://github.com/harfbuzz/harfbuzz/issues/1264
While not regressing: https://github.com/harfbuzz/harfbuzz/issues/1357

That's what Apple does, and it wouldn't degrade our OpenType performance.
