Toggle switch back when user dismisses dialog by tapping screen

The reboot dialog can be dismissed when user:
1) Clicks any button on the reboot dialog
2) Taps any screen area outside of reboot dialog

We want to toggle back the "Enable ANGLE" switch
whenever the user chooses to not reboot the device
immetiately.

This change adds the function to toggle the
"Enable ANGLE" switch back when:
1) User clicks "Cancel" on reboot dialog.
2) User taps screen area outside of reboot dialog
to dismiss the reboot dialog.

Bug: b/270994705
Test: m; flash and device can boot.
