Rollup merge of #124981 - zachs18:rc-allocator-generalize-1, r=Mark-Simulacrum
Relax allocator requirements on some Rc/Arc APIs.

Split out from #119761

* Remove `A: Clone` bound from `Rc::assume_init`(s), `Rc::downcast`, and `Rc::downcast_unchecked` (`Arc` methods were already relaxed by #120445)
* Make `From<Rc<[T; N]>> for Rc<[T]>` allocator-aware (`Arc`'s already is).
* Remove `A: Clone` from `Rc/Arc::unwrap_or_clone`

Internal changes:

* Made `Arc::internal_into_inner_with_allocator` method into `Arc::into_inner_with_allocator` associated fn.
* Add private `Rc::into_inner_with_allocator` (to match Arc), so other fns don't have to juggle `ManuallyDrop`.
