Implement DynSend and DynSync for std::panic::Location.
Allows the compiler to build with the `debug_refcell` stdlib cargo feature.
With `rust.std-features = ["debug_refcell"]` in bootstrap.toml, `./x.py build --stage 2` fails before this patch, and succeeds afterwards.
<details> <summary>error for `./x.py build --stage 2` before this patch</summary>

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).
