1. Restrict what symbols can be used in `#[diagnostic::on_unimplemented]… …

   …` format strings
   
   This commit restricts what symbols can be used in a format string for
   any option of the `diagnostic::on_unimplemented` attribute. We
   previously allowed all the ad-hoc options supported by the internal
   `#[rustc_on_unimplemented]` attribute. For the stable attribute we only
   want to support generic parameter names and `{Self}` as parameters.  For
   any other parameter an warning is emitted and the parameter is replaced
   by the literal parameter string, so for example `{integer}` turns into
   `{integer}`. This follows the general design of attributes in the
   `#[diagnostic]` attribute namespace, that any syntax "error" is treated
   as warning and subsequently ignored.
