Pull Request Overview
This PR removes a workaround in the NPUW (NPU Workload) stateful flow that was offloading SinCos operations to CPU when the context length exceeded 2048 tokens. The workaround is no longer necessary due to accuracy fixes in the NPU plugin and drivers.
Key Changes:
- Removed conditional logic that configured CPU fallback for SinCos operations in contexts >= 2048 tokens
- Simplified the
UpdateNPUConfigfunction by eliminating the threshold check and associated configuration overrides

Description
For stateful NPUW flow, remove the WA where SinCos is offloaded to CPU when MAX_PROMPT_LEN + MIN_RESPONSE_LEN >= 2048
Motivation and Context
This is no longer needed, as there have been accuracy fixes in NPU plugin / NPU drivers.
