Auto merge of #71447 - cuviper:unsized_cow, r=dtolnay
impl From<Cow> for Box, Rc, and Arc These forward `Borrowed`/`Owned` values to existing `From` impls. - `Box<T>` is a fundamental type, so it would be a breaking change to add a blanket impl. Therefore, `From<Cow>` is only implemented for `[T]`, `str`, `CStr`, `OsStr`, and `Path`. - For `Rc<T>` and `Arc<T>`, `From<Cow>` is implemented for everything that implements `From` the borrowed and owned types separately.
