Remove the incomplete marker from `impl` restrictions

Following the discussion on Zulip ([#gsoc > Idea: Implementing impl and mut restrictions @ 💬](https://rust-lang.zulipchat.com/#narrow/channel/421156-gsoc/topic/Idea.3A.20Implementing.20impl.20and.20mut.20restrictions/near/590562763)),this PR removes the incomplete marker from `#[feature(impl_restriction)]`.
Tracking issue for restrictions: rust-lang/rust#105077.
