Rollup merge of #105354 - BlackHoleFox:apple-deployment-printer, r=oli-obk 
Add deployment-target --print flag for Apple targets

This is very useful for crates that need to know what the Apple OS deployment target is for their build scripts or inside of a build environment. Right now, the defaults just get copy/pasted around the ecosystem since they've been stable for so long. But with #104385 in progress, that won't be true anymore and everything will need to move. Ideally whenever it happens again, this could be less painful as everything can ask the compiler what its default is instead.

To show examples of the copy/paste proliferation, here's some crates and/or apps that do:
- [cc](https://github.com/rust-lang/cc-rs/pull/708/files), Soon
-  [mac-notification-sys](https://github.com/h4llow3En/mac-notification-sys/pull/46/files#diff-d0d98998092552a1d3259338c2c71e118a5b8343dd4703c0c7f552ada7f9cb42R10-R12)
- [PyO3](ccb02d1aa1/src/target.rs (L755-L758))
- [Anki](613b5c1034/build/runner/src/bundle/artifacts.rs (L49-L54))
- [jsc-rs](3776726756/xtask/src/build.rs (L402-L405))
... and probably more that a simple GitHub codesearch didn't see

rustc_target contains some very low-level details that are specific to different compilation targets and so forth.
