Usman Akinyemi 0061a2232d rustc_parse_format: improve diagnostics for unsupported debug = syntax ...

Detect Python-style f-string debug syntax in format strings and emit a
clear diagnostic explaining that it is not supported in Rust. When the
intended operation can be inferred, suggest the corresponding Rust
alternative e.g from `println!("{=}", x)` to `dbg!({x})`.
