xcb: minor cleanups around QT_CONFIG(xcb_xlib)

- Remove unused createVisualInfoForDefaultVisualId() function.
  This amends dff3c0f14f3c3a7288c456028d5bec23bee5406a.

- Inline QXcbConnection::xlib_display().

- Don't nest QT_CONFIG(xcb_native_painting) in QT_CONFIG(xcb_xlib).
  configure.json already checks for the dependencies, we don't need
  to do that again in *.h/*.cpp.
