Fix def files so that the implementation agnostic interface definition has no non-standards defined entry points, and change the eglrefimpl specific implementation to place its private entry points high up in the ordinal order space in the implementation region, not the standards based entrypoints region.

/**
MDrawDeviceOrientation interface manages the orientation degrees of CFbsDrawDevice interface.

The interface could be retrieved calling CFbsDrawDevice::GetInterface() with 
KOrientationInterfaceID as an argument.
If the drawing device does not have support for moving origin, MDrawDeviceOrientation cannot be retrieved.
   
MDrawDeviceOrientation interface lifetime is the same as the lifetime of CFbsDrawDevice
interface, which creates it. 
Do not try to delete MDrawDeviceOrientation interface pointer!
   
MDrawDeviceOrientation interface offers following method: 
Orientation()
