CANN: Add MROPE and IMROPE support (ggml-org#17401)

* CANN: ROPE supports both MROPE and IMROPE.

1. Optimize the caching logic of rope_cache_init.
2. Add support for mRoPE and i-mRoPE.

Note that on Ascend 910B devices, it is necessary to disable FA
in CLIP and disable NZ-format conversion. These two issues are
still under investigation.

* Resolve review comments
