[roll] Roll fuchsia [display] Remove support for cursor layers.

Cursor layers currently mix two separate concerns.

1. Movable layers, where CheckConfiguration() would not be needed to
   change the layer's position on the display. Most hardware that we
   support supports having all layers be moveable. Generalizing this
   concept to any Primary layer (where moving would mean changing the
   destination frame's position) would enable applications such as
   dragging windows around the screen in a window manager.

2. Image config hints -- images with specific metadata (size, pixel
   format, stride, etc.) may qualify for special layers. The cursor
   layer on Intel display engine is one example.

This CL removes the current support for cursor layers, which reduces the
cost of ongoing migrations for the display stack. The underlying
functionality can be added again when its benefits outweighs the code
maintenance cost.
