macOS: Support all OpenType font features (#11611)
This PR brings support for all `OpenType` font features to `macOS(v10.10+)`. Now, both `Windows`(with #10756 ) and `macOS` support all font features. Due to my limited familiarity with the APIs on macOS, I believe I have made sure to call `CFRelease` on all variables where it should be called. Close #11486 , and I think the official website's [documentation](https://zed.dev/docs/configuring-zed) can be updated after merging this PR. > Zed supports a subset of OpenType features that can be enabled or disabled for a given buffer or terminal font. The following OpenType features can be enabled or disabled too: calt, case, cpsp, frac, liga, onum, ordn, pnum, ss01, ss02, ss03, ss04, ss05, ss06, ss07, ss08, ss09, ss10, ss11, ss12, ss13, ss14, ss15, ss16, ss17, ss18, ss19, ss20, subs, sups, swsh, titl, tnum, zero. https://github.com/zed-industries/zed/assets/14981363/44e503f9-1496-4746-bc7d-20878c6f8a93 Release Notes: - Added support for **all** `OpenType` font features to macOS.
