Usman Akinyemi 76ad528d32 rustc_parse_format: improve diagnostics for unsupported python numeric grouping ...

Detect Python-style numeric grouping syntax in format strings (e.g. `{x:,}`)
and emit a clear diagnostic explaining that it is not supported in Rust.
This helps users coming from Python understand the error without exposing
the full set of valid Rust format specifiers.
