Suspend and resume DozeTriggers when entering and exiting car mode.

This change introduces a new DozeMachine state DOZE_SUSPEND_TRIGGERS
that is equivalent of DOZE but also suspends any triggers that awaken
the device. Entering car mode transitions the state machine to
DOZE_SUSPEND_TRIGGERS and leaving the car mode transitions to either
DOZE or DOZE_AOD depending on whether Always on Display is enabled.

Current behavior when entering car mode:
  - DozeService is finished.
  - Always on display is turned off
  - Tap on screen doesn’t wake up the device
  - Lifting device doesn’t wake up the device
  - Sending a notification doesn’t wake up the device.

New behavior when entering car mode:
  - DozeService is not finished.
  - Remaining behavior is the same as DozeTrigger stops listening to all
    triggers (sensors, intents, notifications)

Current behavior when exiting car mode:
  - DozeService is not running, normal triggers don't wake up the device

New behavior when exiting car mode:
  - DozeService is running, normal triggers wake up the device as
    expected.
  - DozeSuppressor transitions from DOZE_SUSPEND_TRIGGERS to DOZE/DOZE_AOD
