rustdoc: Replace unstable flag `--doctest-compilation-args` with a simpler one: `--doctest-build-arg` Tracking issue: https://github.com/rust-lang/rust/issues/134172. Context: https://github.com/rust-lang/rust/pull/137096#issuecomment-2776318800 Yeets the ad hoc shell-like lexer for 'nested' program arguments. No FCP necessary since the flag is unstable. I've chosen to replace `compilation` with `build` because it's shorter (you now need to pass it multiple times in order to pass many arguments to the doctest compiler, so it matters a bit) and since I prefer it esthetically. **Issue**: Even though we don't process the argument passed to `--doctest-build-arg`, we end up passing it via an argument file (`rustc `@argfile`)` which delimits arguments by line break (LF or CRLF, [via](https://doc.rust-lang.org/rustc/command-line-arguments.html#path-load-command-line-flags-from-a-path)) meaning ultimately the arguments still get split which is unfortunate. Still, I think this change is an improvement over the status quo. I'll update the tracking issue if/once this PR merges. I'll also add the (CR)LF issue to 'unresolved question'. r?

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).
