Multiple security issues including data race, buffer overflow, and uninitialized memory drop

arr crate contains multiple security issues. Specifically,

1. It incorrectly implements Sync/Send bounds, which allows to smuggle non-Sync/Send types across the thread boundary.
2. Index and IndexMut implementation does not check the array bound.
3. Array::new_from_template() drops uninitialized memory.
