Conditional compilation according manifest MSRV.

# Selectors

- `#[rustversion_msrv::msrv]`

  True on the **call-site** crate's `rust-version` field, i.e., its minimum supported Rust

  version (MSRV).

# Use Cases

The motivating use case for the `msrv` macro in this crate is to ensure a stable compiler error

output when running negative trybuild tests. Guarding your test function like this means you

only need to update the .stderr files when you bump your MSRV, not (potentially) every stable

release (or worse). Of course, try make sure that your CI is actually running an MSRV job in its

set.

```rust

#[rustversion_msrv::msrv]

#[test]

fn trybuild() {

   // ...

}

```
