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.
