  Q: 2. Will the Viltrox EF-L adapter allow full Canon EF lens to Leica CL body communication as well as IS, auto focus and auto aperture setting?

  A: It depends if the specific lens that you are using was setup in the firmware that the adapter has. If it was autofocus, body communication, IS, and auto aperture will work. I don't see a compatibility list online though so only way to know is to try it out.
