[morx] Remove mark_set from Insertion
...
text-rendering-tests test MORX-32 shows that for Insertion, an unset mark is treated
as mark set at 0. This is unlike the Reordering lookup where un unset mark performs
nothing.
Fixes MORX-32.

We reverse too many times. Can be optimized. But I doubt many fonts

Disallow null-enabled offsets to unsized structures...
...
...like UnsizedArrayOf<>.
This fixes a class of crasher bugs, mostly with color and AAT tables. We
cannot use nullable offsets to varsized data that does not declare min_size,
because it's nost safe to use our fixed-size null pool for types that have
their size external. So, use non_null'able offsets for these.
A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.

[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

ugh, extra work to fix. Let me try...
