[code-reflection] RFR: ModuleOp generation from LambdaOp and FuncOp [v8]

[Ruby Chen]

> Add support for generating a ModuleOp from either a LambdaOp or a FuncOp. The given LambdaOp will be converted into the root FuncOp, and the given FuncOp will be assigned as the root FuncOp.
> 
> For `CoreOp.ModuleOp.ofLambdaOp()`, a unique name for the new root FuncOp must be passed as a parameter.
