[cff] Implement in-house power of 10 
A minimal power only for natural numbers exponents of ten, for portability.

Found the idea in Tcl/Tk but wrote it myself after weeks and it turned out
being a different implementation, reverse direction, constexpr, etc.

7eafe94705 Revert "[array] Add chop()" 
This reverts commit 545fe9d9f0.

Breaks gcc 4.8 and MSVC all versions.

Will add hb_chop() that works on all iterators instead.

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.

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.
