hw/xwin: Default to -noresize when -fullscreen is used

Currently, just using -fullscreen fails in winValidateArgs(), as the default
-resize=randr is incompatible with -fullscreen.

Set the default resize mode to -noresize if -fullscreen is used.

Also, rename enum value notAllowed -> resizeNotAllowed for clarity.
