[NPU]: fused_add_rms_norm kernel distinguish the chunking strategy (#1100)

## Summary
<!--- This is a required section; please describe the main purpose of
this proposed code change. --->
Based on #1070 
Because the original kernel uses n_cols as BLOCK_SIZE, and n_cols is
smaller in the test, the test can pass normally. However, in the
benchmark, n_cols is larger, and when running on the NPU, an ub overflow
occurs. Therefore, for each row, we process it in chunks of BLOCK_SIZE.
Maintain high performance even when using a smaller hidden size in most
models, and also ensure support in cases where a larger hidden size is
used.
