[iter/meta] Fix build on newer clang
...
The mystery failure had to do with SFINAE failure because the template
function involved was accessing ::iter_t of a type that was also named iter_t.
In this context, apparently:
warning: ISO C++ specifies that qualified reference to 'iter_t' is a
constructor name rather than a type in this context, despite preceding 'typename' keyword
[-Winjected-class-name]
We use a new macro, also called hb_iter_t(), to get iterator type of
a type. This uses declval/hb_decltype, and has the added benefit
that it returns correct type for const vs non-const objects, if they
have different iterators.

Fix ambiguity of hb_sorted_array_t::item_t with gcc. No idea if that's a gcc bug
or what spec requires, but using aliasing using seems to fix it. It probably breaks
our non-C++11 bots, in which case I have to condition the change. Testing.
