feat(ethos-n): add stream extends and attr support

The SiP service for the Arm(R) Ethos(TM)-N NPU driver will now handle
setting up the address extension and attribute control for the NPU's
streams. The non-secure world will still be allowed to read the address
extension for stream0 but non-secure access to all other streams have
been removed.

The API version has been given a minor bump with this change to indicate
the added functionality.
