  Add gl::RenderbufferState shared state helper.
  
  This shared state will be read-only visible in the RenderbufferImpl
  class. It mirrors existing structs for Textures, Buffers, and other
  classes. It allows the implementation class to have a read-only view
  as to the current GL state of an object.
  
  This will be useful to the Vulkan back-end, which would like to know
  the current Renderbuffer state before having to redefine the storage.
  If the current parameters match, it might not have to redefine the
  storage at all.
  
  The solution involves passing around the gl::RenderbufferState
  through various factory methods.
  
  Also name the Renderbuffer implementation pointer consistently and
  make it use std::unique_ptr.
