NEWT: Align DisplayImpl.createPointerIcon(..) behavior; PointerIconImpl.validatedHandle() shall not create native resource.

Semantic cleanup for clarity and equal behavior

Align DisplayImpl.createPointerIcon(..) behavior
- return null handle of createPointerIconImplChecked(..) shall be accepted,
  no exception for neither of the two creation methods.

PointerIconImpl.validatedHandle() shall not create native resource.
- throws exception if handle is null (about to be used)
- no native creation shall happen here.

Display.PointerIcon.validate(): Removed, not used.
