Auto merge of #124432 - zetanumbers:non_copy_into_raw_with_alloc, r=Nilstrieb

Relax `A: Clone` bound for `rc::Weak::into_raw_and_alloc`

Makes this method to behave the same way as [`Box::into_raw_with_allocator`](https://doc.rust-lang.org/1.77.2/alloc/boxed/struct.Box.html#method.into_raw_with_allocator) and [`Vec::into_raw_parts_with_alloc`](https://doc.rust-lang.org/1.77.2/alloc/vec/struct.Vec.html#method.into_raw_parts_with_alloc).

I have also noticed the inconsistent presence and naming, should probably be addressed in the future.
