Add API (backed by Setting) to enable/disable volume changes via HDMI
CEC for HDMI CEC source devices.
This state is persisted via Settings.

If volume control is disabled, no incoming HDMI CEC commands related to
volume will be processed. If disabled, no HDMI CEC volume control
messages will be sent by the device.

When the mode of navigation bar is system gesture mode, there is
a navigation bar inset existing, but the application can not touch
this region due to all touch events from this region received by
launcher. We need to account this region with unaccount space to
avoid the windows which could not be touched passing to A11y
framework.

If a relaunch-attempt is made on the app in a minimized
primary-split, just expand it. This way its clear to the user
what happened and is much closer to their intent. Previously,
this was just opening recents; however, that doesn't make sense
for pixel launcher (which remains in minimized-dock even with
recents active) because the actual launched-app is still
not-focusable and partially obscured.

Also, modified the restart-attempt logic to directly check if
divider is minimized rather than homeTaskVisible since that is
semantically what matters.

Now that we don't have a re-used pinned stack anymore, this is
how it should be. This also helps CTS align closer to actual
app usage.

Also don't perform transactions on detached containers (but log
an error). This is because CTS triggers various pip events which
fire callbacks after the test tears-down.

Steps to reproduce the bug:
- Restart the device
- Open Duo app and make a call
- When in call, try entering PiP

Duo application contains multiple activities and we create a new stack
from its top activity when moving it to pinned mode. This newly created
stack does not carry on the existing PictureInPictureParams, nor it is
marked as visible. Therefore, no onTaskAppeared would be sent to the
task organizer.

Also in this change:
- Removed aspectRatio and sourceHintBounds used to be passed into
  RootWindowContainer#moveActivityToPinnedStack, they are used in
  moveActivityToPinnedStack and one should refer to the
  PictureInPictureParams set on ActivityRecord
- Added a null check for existing token when onTaskInfoChanged is
  invoked in PipTaskOrganizer, it should be a fatal error that
  onTaskInfoChanged is called ahead of onTaskAppeared
