  Refactor
  
  Bind the interface on abstract-egl level. Then we can remove the interface
  stubs throughout the stack.
  
  The interface is not created when EGL format extensions are not available
  or we don't use EGL.
  
  Let the impl be the main class creating the interface, the impl is then
  destroyed from the interface on destruction of the abstract-egl-backend.
  
  Set supported formats and modifiers once in the beginning and remember them
  in the KWayland interface private part. The according KWayland interface
  has been adapted.
  
  This code is still missing support for multi-plane buffers. We need it because
  while we can filter out multi-plane formats modifiers might add additional
  planes (for example i915 Y_TILED_CCS) to otherwise single-plane formats.
