[Feature Request] Add SwiGLU support for Qwen3-VL models

Problem Description

Can we add SwiGLU kernel support for Qwen3-VL models in Liger-Kernel?

Currently, it appears that passing swiglu=True in the apply_liger_kernel_to_qwen3_vl monkey patch function is a no-op and does not activate the kernel.
