Update supported models for Liger Kernel (#1875)

* Update supported models for Liger Kernel

Add Mistral LCE, Gemma LCE, Gemma 2 without LCE (softcapping is not yet implemented for Gemma in Liger Kernel LCE forward), Phi3 without LCE

* move import to their appropriate conditions

* Integrate Phi3 LCE support
