Stabilize RefCell::try_borrow_unguarded
Servo has been using this since https://github.com/servo/servo/pull/23196 to add a runtime check to some unsafe code, as discussed in PR https://github.com/rust-lang/rust/pull/59211. Stabilizing would help do more of the same in libraries that also have users on Stable.
