bf7e27a4 - [WebNN EP] Remove unnecessary cast around normalization ops (#29024)

[WebNN EP] Remove unnecessary cast around normalization ops (#29024) Remove fp16→fp32→fp16 cast workaround from SimplifiedLayerNormalization and SkipSimplifiedLayerNormalization. The WebNN backend now handles float16 precision correctly, making these intermediate casts unnecessary.
