Add vr persistent mode enable/disable

Persistent vr mode toggle control is needed sometimes from command line.
This also adds the infrastructure for future vr commands.

Bug: 36071574
Test: adb shell vr set-persistent-vr-mode-enabled true
      adb shell dumpsys vrmanager
      >> Persistent VR mode is currently: enabled
      adb shell vr set-persistent-vr-mode-enabled false
      adb shell dumpsys vrmanager
      >> Persistent VR mode is currently: disabled
