Add more missing properties/methods to the converter.

icon_align -> icon_alignment
rect_min_size -> custom_minimum_size
get_tree().set_input_as_handled() -> get_viewport().set_input_as_handled()
_unhandled_key_input(event: InputEventKey) -> _unhandled_key_input(event: InputEvent)
And C# equivalents
