Add lint converting reference to pointer cast into `ptr::from_{ref,mut}` method calls

[SUPERCILEX]

What it does

&something as *const Something would be converted to ptr::from_ref(&something)

See the tracking issue: rust-lang/rust#106116

Once those methods are stabilized, we should be able to re-open #9802 and finally ban all as casts for pointers.
