[kernel] add AscendC op: lightning_indexer and sparse_flash_attention (#4625)
### What this PR does / why we need it? Provide high-performance AscendC operators lightning_indexer and sparse_flash_attention to boost the execution performance of the DeepSeek v3.2 model. Meanwhile, adapt the two AscendC operators to vllm-ascend framework. ### Does this PR introduce _any_ user-facing change? No (only underlying operator optimizations, with no user-facing changes) ### How was this patch tested? - vLLM version: v0.11.2 - vLLM main: https://github.com/vllm-project/vllm/commit/v0.11.2 Signed-off-by: MingYang119 <songmingyang@huawei.com>
