Bug 1528042 - Add successful gUM calls to existing WPT and mochitests…

… to let them continue to test full device information exposure in enumerateDevices(). r=karlt

This is required by spec. See
w3c/mediacapture-main#641 and
w3c/mediacapture-main#773 for details.

Also fixes test_enumerateDevices_getUserMediaFake.html to run on macOS outside automation.
