Proposal for `Box::new_uninit_array` and `Box::new_zeroed_array`

A proposal on Rust Internals suggests introducing `Box::new_uninit_array` and `Box::new_zeroed_array` methods. These methods aim to provide a more efficient way to allocate uninitialized or zeroed arrays on the heap. By leveraging Rust's safety guarantees, these additions could simplify memory management and potentially enhance performance in scenarios requiring large array allocations. This proposal is particularly relevant for developers dealing with low-level memory management in Rust.
