[NTUSER] Fix SetProcessDefaultLayout() (#1013)

Browse source 
- Add a check in co_UserCreateWindowEx() for parentless windows,
  that checks the default layout direction; if it's LAYOUT_RTL
  add the WS_EX_LAYOUTRTL flag to the extended window styles.

- Make the internal routine accepting also LAYOUT_LTR as a value for SetProcessDefaultLayout().
  Limit receiving value to LAYOUT_ORIENTATIONMASK (and not just LAYOUT_RTL)
  or LAYOUT_LTR, as per written in:
  https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-setprocessdefaultlayout

Now all the applications that call SetProcessDefaultLayout() to mirror the layout get mirrored.
This is based on Wine.
