Test codegen when setting deployment target

Test our codegen in different scenarios when setting the deployment target. There are many places here where this is still incorrect, these will be fixed in rust-lang/rust#129342, rust-lang/rust#129367 and rust-lang/rust#129369. See rust-lang/rust#129432 for the bigger picture.

Tested locally using:
```console
./x test tests/run-make/apple-deployment-target --target="aarch64-apple-darwin,aarch64-apple-ios,aarch64-apple-ios-macabi,aarch64-apple-ios-sim,aarch64-apple-tvos,aarch64-apple-tvos-sim,aarch64-apple-visionos,aarch64-apple-visionos-sim,aarch64-apple-watchos,aarch64-apple-watchos-sim,arm64_32-apple-watchos,armv7s-apple-ios,i386-apple-ios,x86_64-apple-darwin,x86_64-apple-ios,x86_64-apple-ios-macabi,x86_64-apple-tvos,x86_64-apple-watchos-sim,x86_64h-apple-darwin"
```

The only Apple targets that aren't tested by the above command are:
- `arm64e-apple-darwin`, failed to build, see rust-lang/cc-rs#1205.
- `armv7k-apple-watchos`, failed to link, see rust-lang/rust#130071.
- `arm64e-apple-ios`, failed to link, see rust-lang/rust#130085.
- `i686-apple-darwin`, requires a bit of setup and an older machine, see [the docs](https://doc.rust-lang.org/nightly/rustc/platform-support/i686-apple-darwin.html).
- `i386-apple-ios` requires you to set `IPHONEOS_DEPLOYMENT_TARGET=10.0` for the test helpers to work, will be fixed by rust-lang/cc-rs#1030.

But all of this is as it was before this PR.

Fixes rust-lang/rust#47825, since we now have a test that compiles a `dylib` for `aarch64-apple-ios`.

Split out from rust-lang/rust#129342, see that for a little bit of the review that this has gone through already.
