Rollup merge of #23844 - kvark:try_unique, r=alexcrichton
While trying to implement parallel ECS processing, I stumbled upon the need to mutate `Arc` contents. The only existed method that allowed that was `make_unique`, but it has issues: - it may clone the data as if nothing happened, where the program may just need to crash - it forces `Clone` bound, which I don't have The new `try_unique` allows accessing the contents mutably without `Clone` bound and error out if the pointer is not unique.
