Fix dynamic handling of view op in OpenVINO backend and enable get_row

[zhaixuejun1993]

This pull request improves the handling of "view" inputs in the OpenVINO backend, specifically for the get_rows operation. The update introduces a more robust and unified approach for processing view inputs, enabling more efficient slicing when possible and simplifying the overall logic. The most important changes are grouped below:

Improved handling of view inputs

• Replaced the legacy logic in openvino/op/get_rows.cpp to always process both data and indices inputs using the new process_view_input_new function, ensuring consistent handling regardless of input source.
• Enhanced process_view_input_new in openvino/utils.cpp to detect when a view can be represented as a simple slice along a single dimension, and to generate an efficient Slice node in those cases, improving performance and clarity.

Cleanup and compatibility

• Removed GGML_OP_GET_ROWS from the set of operations that do not support view inputs in ggml-openvino.cpp, reflecting the improved support for views in the updated logic.…enable view + get_row
