Actually both are references to a very old game (Castlevania), which contained the mythical Goat Teleporter. It became a sort of internal Google meme/in-joke used whenever you needed some arbitrary object in an example. Goat teleporters show up in a few places in Google-external material, not just Chrome and Android. I recall them being occasionally mentioned when I worked there too, though it's been many years and I forget exactly how it got started.

If you search for it you'll find all the references are by Google except one or two (which are probably ex-googlers repeating the meme):

Yeah, it did O.o

  2249  public boolean isUserAGoat() {
  2250     if (mContext.getApplicationInfo().targetSdkVersion >= Build.VERSION_CODES.R) {
  2251        return false;
  2252     }
  2253     // Caution: This is NOT @UserHandleAware (because mContext is getApplicationContext and
  2254     // can hold a different userId), but for R+ it returns false, so it doesn't matter anyway.
  2255     return mContext.getPackageManager()
  2256        .isPackageAvailable("com.coffeestainstudios.goatsimulator");
  2257  }
