GLProfile/NativeWindowFactory: Remove deprecated argument 'firstUIActionOnProcess' of initSingleton() method

The notion of changing the threading behavior of native initialization was deprecated for over a year.
The code still contained the bits and pieces, i.e. whether X11Util.initSingletion() is invoked
before or after optional AWT initialization.
This condition has been removed now and behavior is uniform, i.e.
X11Util.initSingletion() is invoked after optional AWT initialization.

- Removed GLProfile.initSingleton(boolean firstUIActionOnProcess), use remaining GLProfile.initSingleton()

- Removed NativeWindowFactory.isFirstUIActionOnProcess()

- Changed NativeWindowFactory.initSingleton(boolean firstUIActionOnProcess) to
          NativeWindowFactory.initSingleton()
