[avar] Fix out-of-bound read when input is bigger than all the coords
...
'i' shouldn't become equal to array's length which as the increament
is happened at end of the loop, if the input is bigger than all the
table coords, it will be equal to array's length.

collect_unicodes() with clamp, calling add_range()
...
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.
Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.

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.

[test] Remove not-fixed yet testcases ( #1268 )

I added them but now that I think, it is a bad idea to have them as
fuzzing bots will find good seeds to tweak in order to find easy new
testcases which causes duplicated issues.
