Add the "memcpy" doc alias to slice::copy_from_slice [RFC1419](https://github.com/rust-lang/rfcs/pull/1419) describes `slice::copy_from_slice` as a "safe memcpy". This enables people searching for `memcpy` to find the `slice::copy_from_slice` method. Thanks! ## Screenshots This is currently the output when searching for "memcpy" -- `copy_from_slice` is safe, and should be part of this list. ![Screenshot_2020-11-19 Results for memcpy - Rust](https://user-images.githubusercontent.com/2467194/99722964-c9e8fe80-2ab1-11eb-82a5-4afe703a0eea.png)
