1. Add methods to create a HandleValueArray. …

   Rust-mozjs currently does not define any methods to create instances of HandleValueArray.
   Consequently, consumers have to create these instances manually. This is unnecessary boilerplate,
   and therefore should be abstracted behind a function.

2. Implement `AsHandle` and `AsHandleMut` traits. …

   Several types in rust-mozjs, such as Heap, PersistentRooted, and RootedGuard, represent a rooted
   value. A common property of rooted values is that a handle can be obtained to it. Rather than
   implement this property separately for each of these types, we should abstract it out into these
   two traits.
   
   This has several advantages: for instance, one can write functions that take any rooted value as
   argument, regardless of how it is implemented, and then obtain a handle to it. Additionally, it
   allows one to implement these traits for newtypes which underlying type is a rooted value.
