[EPLB][Ops] Integerate grouped_matmul_swiglu_quant_weight_nz_tensor_list operator into dynamic EPLB (#4216)

Browse Source 
### What this PR does / why we need it?
Integerate grouped_matmul_swiglu_quant_weight_nz_tensor_list into
dynamic EPLB to support list-type parameters
This PR also modify the logic of loading model in dynamic-eplb scenario.
The operator is based on this pr:
https://github.com/vllm-project/vllm-ascend/pull/3804

### Does this PR introduce _any_ user-facing change?
no
### How was this patch tested?
