Rollup merge of #139850 - xizheyin:issue-138698, r=jieyouxu

Hide unstable print kinds within emit_unknown_print_request_help in stable channel

Fixes #138698

We need to get the channel from `matches`. However, since `matches`(Line 1169) is constructed after `rustc_optgroups` (Line1165, where `RustcOptGroup::value_hint` is generated, i.e. what `rustc --print print` prints), I've left it unchanged here for now.

https://github.com/rust-lang/rust/blob/2da29dbe8fe23df1c7c4ab1d8740ca3c32b15526/compiler/rustc_driver_impl/src/lib.rs#L1161-L1169

There is actually a way to manually parse the `--crate-name` parameter, but I'm afraid that's an unorthodox practice. So I conservatively just modified `emit_unknown_print_request_help` to print different parameters depending on whether they are nightly or not when passing the error parameter.

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).
