GLDrawable: Refine API doc; GLDrawableImpl: Balance createHandle()/destroyHandle(); Handle LOCK_SURFACE_CHANGED in lockSurface() ; GLContextImpl.makeCurrent(): Fix drawable handle validation.

GLDrawable: Refine API doc (realized/handle)
  - Lifecycle of the drawable handle was not clear
  - Ephasizing handle's dependency on NativeSurface's lock state and drawable's realization

GLDrawableImpl: Balance createHandle()/destroyHandle()
  - updateHandle() -> createHandle()
  - ensure both are balance, see below

GLDrawableImpl: Handle LOCK_SURFACE_CHANGED in GLDrawableImpl's lockSurface()
  - call destroyHandle() and createHandle()

GLContextImpl.makeCurrent(): Validate drawable handle if realized only.
  - it is valid to have an invalid drawable handle if not realized (see above)
