Enable T5 model for architecture testing in OpenVINO backend

[zhaixuejun1993]

This pull request makes targeted changes to the ggml-decoder.cpp file, focusing on error handling and logic for specific operation cases in the decoder. The most important changes are:

Error Handling Adjustments:

• Commented out a runtime exception in compute_op_case for unsupported VIEW cases, which prevents the decoder from throwing an error and allows it to continue execution in this scenario.

Logic Improvements for Mask Handling:

• Added assignment of the mask variable in the case where case 3 is handled in compute_llm_params, ensuring that the mask is correctly set for downstream logic.
• Updated the condition to continue processing only if cache_k_view->op is GGML_OP_VIEW and mask is not null, improving robustness in the handling of model parameters.## Overview
