Enable Blade on MacOS via "macos-blade" feature (#7669)

Depends on https://github.com/zed-industries/font-kit/pull/2 and
https://github.com/kvark/blade/pull/77

This change enables Blade to be also used on MacOS. It will also make it
easier to use it on Windows.

What works: most of the things. Zed loads as fast and appears equally
responsive to the current renderer.

Things missing:
- [x] video streaming. ~~Requires a bit of plumbing on both Blade and
Zed sides, but all fairly straightforward.~~
  -  verified with a local setup
- [x] resize. ~~Not sure where exactly to hook up the reaction on the
window size change. Once we know where, the fix is one line.~~
- [ ] fine-tune CA Layer
- this isn't a blocker for merging the PR, but it would be a blocker if
we wanted to switch to the new path by default
- [ ] rebase on latest, get the dependency merged (need review/merge of
https://github.com/zed-industries/font-kit/pull/2!)

Update: I implemented resize support as well as "surface" rendering on
the Blade path (which will be useful on Linux/Windows later on). I
haven't tested the latter though - not sure how to get something
streaming. Would appreciate some help! I don't think this should be a
blocker to this PR, anyway.

The only little piece that's missing for the Blade on MacOS path to be
full-featured is fine-tuning the CALayer configuration. Zed does a lot
of careful logic in configuring the layer, such as switching the
"present with transaction" on/off intermittently, which Blade path
doesn't have yet.

Release Notes:
- N/A
