ggml-webgpu: port all AOT operators to JIT (#20728)

* port cpy pipeline to shader lib with JIT compilation * port glu pipeline to shader lib with JIT compilation * port rope pipeline to shader lib with JIT compilation * port soft_max pipeline to shader lib with JIT compilation * removed unused functions from embed_wgsl.py which were used for old AOT template expansion
