Replace objc with objc2 in other projects

[madsmtm]

As part of moving towards a (somewhat stable) version, I'd like to submit PRs to other projects to set an ecosystem-wide precedence for using this crate, and to see which patterns people are actually using that objc2 doesn't (or doesn't easily) help with.

As soon as metal-rs merges the PR you replaced with objc2, I'm interested in completing the wgpu-hal part

Mentioning https://github.com/norse-rs/raw-window-metal since ash-window depends on it.
