Consistent name for CompositeToLayoutOp

[jnie-TT]

Followup issue from #840, we want to have a ToLayout op that captures all the parameters up front, effectively doing what the current CompositeToLayoutOp does (maybe set a couple parameters as optional since ttnn::to_layout miight not support them yet), and we would just use the same op for tilize/untilze. And eventually we can merge the decomposed ops into this op as ttnn supports them, and make subsequent arguments required instead of optional.
