Adding initialTime parameter to MacosTimePicker

[Abbas1Hussein]

I have added the initialTime parameter to the MacosTimePicker widget, allowing to set an initial time value for the picker.

Minor Change: Added a void return type to OnDateChanged and OnTimeChanged.

The change has been tested to ensure proper functionality.
