gl: Use GstGLDisplayEGL directly instead of creating a GstGLDisplayVIVFb subclass

Browse source 
This simplifies the code a lot without any functional changes apart from
not closing the display connection. Closing the display connection is
not safe to do as it is shared between all other code in the same
process and no reference counting or anything happens at the platform
layer.
