Devices exist (specifically the 16GB 5th generation iPod Touch) that do not have a rear-facing camera. This CL: - Adjusts RTCAVFoundationVideoCapturerInternal so initialization doesn't fail because a rear-facing camera doesn't exist, but still logs a warning - Provides a check for whether or not a rear-facing camera can be used (useful for toggling UI elements) - Turns an attempt to switch to the rear-facing camera into a no-op with a warning.
