GLDrawableFactory*.createOffscreenDrawable(): No implicit setRealized(true) @ creation

GLDrawableFactory*.createOffscreenDrawable():
No implicit setRealized(true) @ creation, following deferred creation like onscreen drawables.
This allows using offscreen drawables in classes like GLCanvas, where realization is deferred due to pending valid size.
Only createGLPBuffer() realizes the offscreen pbuffer drawable immediatly to reduce the impact
on user-code.

GLDrawableFactoryImpl.createGLDrawable():
  - Simplify OffscreenLayerSurface validation and check it first regardless of the chosenCaps
    to get a chance to use pbuffer.
