Rescope unsafe fn blocks

[sftse]

To narrow down the causes of the observed crashes, let's rescope the unsafe use to a smaller area.

Objc2-foundation made mostsome of its bindings safe, so here is a first batch of changes.

Most of the diff is dumb indentation changes, split out as a fmt commit.

Objc2-foundation made most of its bindings safe

iirc at least some of that (thinking of all objc2 crates) wasn't in 0.6.0 / 0.3.0 so we should probably increase the minimum patch version of the objc2 crates or check if =0.3.0 still compiles

[sftse]

=0.3.0 would not compile. I think the logic of the change is that making methods safe is purely backwards-compatible.

I did a rough smoke-test to check what cargo does. If we do note the patch version explicitly in the Cargo.toml, as done in this PR, it seems to treat it as a hard >=0.3.2 constraint, so dependency alignment means any downstream consumer of wry will update their locked version to >=0.3.2.

I think this update could only cause problems if we have a floating patch number like 0.3 in wry's Cargo.toml.

[FabianLars]

ay sorry, the cargo.toml change didn't load on my phone. didn't notice that you already upped the version. Do any of the other objc2 crates need a bump as well?

[sftse]

Let's try.
