Update to Xcode 26.2
Update our CI to run with Xcode 26.
This means that:
- LLVM will be built with a newer Clang version (before Apple Clang 15, now Apple Clang 17).
- Our binaries (e.g. `rustc` and `libstd*.dylib`) will have their SDK version raised (before macOS 14.5, now 26.2).
- Our binaries will be built with a newer linker (before 1053.12, now 1230.1).
The last two points can be observed with:
```sh
$ vtool -show-build ./build/host/stage1/bin/rustc
Load command 10
cmd LC_BUILD_VERSION
cmdsize 32
platform MACOS
minos 11.0
sdk 26.2
ntools 1
tool LD
version 1230.1
$ vtool -show-build ./build/host/stage1/lib/rustlib/aarch64-apple-darwin/lib/libstd*.dylib
Load command 9
cmd LC_BUILD_VERSION
cmdsize 32
platform MACOS
minos 11.0
sdk 26.2
ntools 1
tool LD
version 1230.1
```
This shouldn't have much of an effect, but things like `dyld` is known to inspect the SDK version, so it _might_ expose some latent bugs (I really don't expect it to though).
This also updates the macOS runners to run on macOS 15 (the macOS 14 runners only have up to Xcode 16.2 available). That is desirable anyhow, as [the macOS 14 runners will be deprecated in July](https://github.com/actions/runner-images/issues/13518). This is probably also required for https://github.com/rust-lang/rust/pull/147192.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
