68c1798a67 [coretext] Use kCTFontOpenTypeFeatureTag 
Instead of trying to map OpenType features to AAT feature selectors
which only works for a small subset of OpenType features, use the
simpler kCTFontOpenTypeFeatureTag with OpenType feature tags directly.

With this change, features like cvXX can be enabled in coretext shaper,
while they were previously ignored due to missing mapping.

This seems to work even with AAT fonts that don’t have OpenType layout
tables, which suggests that CoreText is doing the mapping itself in this
case.

kCTFontOpenTypeFeatureTag seems to have been introduced in macOS 10.10
and iOS 8.0, though, so its use is conditional on version check for now.
Not sure how to check iOS version, so I left this out.

b79ceac3c6 Prefer UINT_MAX instead of uint overflow. 
Also, prefer HB_FEATURE_GLOBAL_START and HB_FEATURE_GLOBAL_END.

b618e0ae13 Remove non-breaking spaces from comments. 
`0xC2A0` was used, for some reasons. It's not really a problem, but Qt Creator
constatly trying to replace them with regular spaces, so I have to edit those
files separately.

780d640c02 Remove unnecessary check in hb_buffer_t::set_masks. 
Bounds are already checked by the caller.

Closes #2073
