Remove the safe_suggestion feature

This removes the safe_suggestion feature from feature_gate.rs.
It was added in commit 164f0105bb65f31b89e5fb7f368c9e6f5833a3f8
and then removed again in commit c11fe553df269d6f47b4c48f5c47c08efdd373dc .

As the removal was in the same PR #38099 as the addition, we don't move it to
the "removed" section.

Removes an element from the whitelist of non gate tested unstable lang features (issue #39059).
