Remove the extra parameters in onCommitNotComposited

The PhysicalDisplayId parameter of the onCommitNotComposited function is passed by value. PhysicalDisplayId is a structure, but the parameter value is never used inside the onCommitNotComposited function, which will cause a certain amount of memory waste. You can remove this parameter first, or change it to reference passing. (But reference passing here should not be necessary).
