Usman Akinyemi b0e65da2af rustc_parse_format: improve error for missing : before ? in format args ...

Detect the `{ident?}` pattern where `?` is immediately followed by `}` and emit
a clearer diagnostic explaining that `:` is required for Debug formatting.
This avoids falling back to a generic “invalid format string” error and adds
a targeted UI test for the case.
