CANN: Improve device ID handling and aclnnArange checks (#16752)

* cann: improve device ID handling and aclnnArange checks

- Stop relying on CANN's internal device ID retrieval; use a global variable instead.
- Enforce stricter dimension validation in aclnnArange for better compatibility across CANN versions.

* cann: use thread local var
