May or may not be used in https://github.com/harfbuzz/harfbuzz/pull/1432

...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.

Sorry for the noise, downstream custom builders.  Please adjust.

DEFINE_SIZE_MIN is to be used only in rare cases. For fixed-size structs
we want DEFINE_SIZE_STATIC.

Ops, this was done for testing
