Cleanup GLDrawableFactory API and platform Implementations

- Finish API change using the AbstractGraphicsDevice, which denotes the target device
  for the desired NativeSurface / GLDrawable.
  The AbstractGraphicsDevice argument may be null to reflect the platform's default device.
  Clarified API documentation.
  This move is necessary to make the API coherent.

- createOffscreenDrawable(..) may create a Pbuffer drawable if caps and supported.
  This unifies the functionality with createGLDrawable(..).
  Further more, a Pbuffer drawable is an offscreen as well.

- added createOffscreenSurface(..) following the same behavior as createOffscreenDrawable(..),
  this is a convenient native offscreen surface factory entry.

- removed createGLPbufferDrawable(..), use createOffscreenDrawable(..),
  since it is redundant!

Implementation Details:

- EGLDrawableFactory holds a shared native EGLGraphicsDevice,
  being used by the offscreen EGL drawable (no more multiple creation).
