Behdad Esfahbod 545fe9d9f0 [array] Add chop()
Takes n, and returns iterator of iterators that contain up to
n items each.  Basically cuts the array into subarrays of size n.
The last sub-array might contain fewer.

Ideally this should become a generic iter tool, not array-specific,
so we can use it in GPOS to chop a value matrix into rows and elements.

Behdad Esfahbod c72589f13f [iter] Change item_size to get_item_size()
By moving access to hb_static_size(Type) into a function instead of
a class-const, we can refer to iter types of incomplete types, which
come handy when a method of hb_array_t wants to return iterator
of hb_array_t.  That kind of stuff.   Next commit needs this to
build on clang...

[subset] Raise the bar in new vs old table size
https://crbug.com/oss-fuzz/16740

This is actually an interesting thing that {h,v}mtx allocates as
much as a font pretends to have glyphs but the solution is not
that obvious as regular fonts can have less than actually containing
metrics in their {h,v}mtx. This change raises the bar to consider this
hmtx 4 byte for every glyph case.

Initially we wanted to just find things allocating crazy amount of
memory but having the assert has led to interesting findings also
so let's don't remove the assert and see what we can find elsewhere.

Remove hb_directwrite_shape_experimental_width public API
I had specially exposed the API as I didn't know how to embed harfbuzz
easily elsewhere but now with harfbuzz.cc it has become very easy
and I don't like to see its use anywhere as it has a bad naming and
its Kashida adding is bogus and only useful to check where it should
be added, not visually useful however.
