Rollup merge of #91804 - woppopo:const_clone, r=oli-obk
Make some `Clone` impls `const`

Tracking issue: #91805
`Clone::clone_from` and some impls (Option, Result) bounded on `~const Drop`.

```rust
// core::clone
impl const Clone for INTEGER
impl const Clone for FLOAT
impl const Clone for bool
impl const Clone for char
impl const Clone for !
impl<T: ?Sized> const Clone for *const T
impl<T: ?Sized> const Clone for *mut T
impl<T: ?Sized> const Clone for &T

// core::option
impl<T> const Clone for Option<T>
where
    T: ~const Clone + ~const Drop

// core::result
impl<T, E> const Clone for Result<T, E>
where
    T: ~const Clone + ~const Drop,
    E: ~const Clone + ~const Drop,

// core::convert
impl const Clone for Infallible

// core::ptr
impl<T: ?Sized> const Clone for NonNull<T>
impl<T: ?Sized> const Clone for Unique<T>
