Add DISABLE_CLOCK flags to status bar, fix transitions

- CollapsedStatusBarFragment now listens to DISABLE_CLOCK so that it can
be requested to hide with disable flags (fixes SUW)
- PhoneStatusBarTransitions cares about the entire left side as a unit
instead of just notifications.

Test: atest frameworks/base/packages/SystemUI/tests/src/com/android/systemui/statusbar/phone/CollapsedStatusBarFragmentTest.java
Test: go through SUW, also change users from guest -> owner from lock
screen.
