Allows to use wrappers other than Box to build ArrowArrayStreamReader.

[Qqwy]

Before, only Box was supported by ArrowArrayStreamReader.

This PR enables support for ArrowArrayStreams which are:

• stack-allocated rather than boxed (plain ArrowArrayStream);
• not owned (&mut ArrowArrayStream);
• wrapped in a Box<ArrowArrayStream, CustomAllocator>;
• wrapped in a Box-like type other than std::alloc::Box;
• wrapped in an Arc<Mutex<>>
• etc.

This is especially important when we receive a *mut ArrowArrayStream from C (or anywhere else outside of Rust) as it will need to be cleaned up in the correct way, so a normal Box does not cut it.
