[Feature] Add avx-based kimi-k2 support (#1656)
* support Kimi-K2-Thinking original weight
fix amx kernel bug

* update k2 avx kernel.

* feat: add CPUInfer write buffer task

* [feat]: add kimi k2 cpu write buffer support

- Implement write_weights_to_buffer function in k2-moe.hpp for extracting GPU expert weights
- Fix down (w2) weight column-wise slicing for different TP configurations
- Support three TP scenarios: cpu_tp == gpu_tp, cpu_tp > gpu_tp, cpu_tp < gpu_tp
- Add comprehensive test cases for weight extraction validation
- Ensure compatibility with Kimi model's MoE architecture

* [fix]: correct write_weight_scale_to_buffer expert offset calculation

Fixed the bug in write_weight_scale_to_buffer_task where expert offsets in GPU buffers were incorrectly calculated. Changed from using per_expert_gpu sizes to using full gpu_tp sizes, ensuring correct memory layout for multi-expert scenarios.

Also added benchmark scripts for k2 moe and write buffer operations, and cleaned up debug output in test files.
