Nicholas Nethercote cf0c2c7333 Convert proc_macro_back_compat lint to an unconditional error.
We still check for the `rental`/`allsorts-rental` crates. But now if
they are detected we just emit a fatal error, instead of emitting a
warning and providing alternative behaviour.

The original "hack" implementing alternative behaviour was added
in #73345.

The lint was added in #83127.

The tracking issue is #83125.

The direct motivation for the change is that providing the alternative
behaviour is interfering with #125174 and follow-on work.
