[aat] Fix unsafe-to-break
...
At any position, if state is not zero, mark unsafe-to-break before,
unless we can reason it safe.
At any position, if there's an action entry for end-of-text, mark
unsafe to break.
Also changes buffer diff impl to allow for flag differences as long
as the buffer glyph flags are superset of reference glyph flags.
With this, all MORX tests pass.

With this, MORX-20 passes if I turn --verify off. Our unsafe-to-break
logic is currently broken in presence of end-of-text actions. That's,
ugh, extra work to fix. Let me try...

If the `calloc` for `gsub_accels` or `gpos_accels` fails, then the
unlikely branch afterwards can be taken, which frees up the
`hb_ot_layout_t`, but since those fields can now be `nullptr`, then
we don't want to dereference them.
