d419a9a437 [iter] Use different SFINAE scheme to make MSVC happy 
From Orvid King: TLDR; MSVC has some issues using sizeof(declval<T>()) for
SFINAE of templated types, so I just used SFINAE in a different context where
MSVC doesn't have the issue.

b6f29bf141 [iter] Accept pointers in hb_iter() 
No idea how to avoid dupicating code.  Was hoping hb_deref_pointer()
would do it, but looks like a pointer can't bind to a universal
reference T&&.  Humm.

e5d6fe9782 Don't skip setting the .end field of the first range 
Fixes a bug in CoverageFormat2::serialize whereby the first range
was not serialized correctly if it consists of only a single glyph ID.
This broke shaping of U+0626 in the Arabic fallback shaper, because it
is not found in the coverage table of the 'init' and 'medi' lookups.

Also fix similar bug in ClassDefFormat2::serialize, noted during code
inspection (I haven't observed a case that was actually affected by
this, but it looks broken).

Remove coretext_aat shaper (#1581) 
coretext_aat was a temporary shaper to redirect shaping of AAT fonts
to CoreText and leaving the rest for HarfBuzz.  As HarfBuzz now supports
AAT and Chrome now actually ships that on a stable version on macOS,
we no longer care about such use-case.  If a client really wants 100%
metrics compatibility with CoreText better to use it directly or through
our API.  Replicating the same behavior still is possible using
hb_shape_full, something we don't care or like to offer anymore.
