cros: Move system tray delegate widget container code to SystemTrayClient

cros: Move system tray delegate widget container code to SystemTrayClient

I need this for a follow-up CL to place the Wi-Fi connect/password dialog in
the correct window container for mash.

Also collapse two very similar copies of code to compute the container id and
use the SessionManagerClient directly to get the lock screen state, rather
than tracking it via notifications.

BUG=647412
TEST=none
