  EGL: Add ID types for egl::Surface and egl::Image.
  
  This is in preparation for using resource maps for Context, Surface
  and EGLImage. The map change will make it much easier to work with
  the trace fixture. It will also have a small benefit in safety as
  we will longer be casting raw pointers for these types.
  
  As these objects are used in a lot of places, and simplified C
  can't handle unordered_map, it's necessary to index the maps by
  simple packed IDs in capture/replay code.
