[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.

[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...
