Eric Huss 5f5ad05d80 Add the future edition ...

This adds support for the "future" edition which was added to rustc in
https://github.com/rust-lang/rust/pull/137606.

To enable support for unstable editions, this introduces a new
`unstable-editions` cargo feature. The intent is that instead of having
a new feature for each edition that we reuse this feature for all new
editions. I don't see a particular reason we should have a separate one
for each edition, and this helps a bit with scalability and simplifies
some of the edition process.

This also includes a change to rework `supports_compat_lint` explained
in the comment.
