Add ExtendFromSlice trait At Parity we tried to switch from our internal `elastic-array` crate (which has soundness and ergonomics issues) to `smallvec` but the PR that attempted this replaced `extend_from_slice` calls with `push` loops (which are much slower). We could fix this internally, but the discussion around it made me wonder if this would be something that could be useful upstream. <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/rust-smallvec/54) <!-- Reviewable:end -->
