Also adds some additional debugging: `adb shell dumpsys activity service SystemUI` will now dump the plugin map. This will help us discover leaks that happen to interact with plugins, or leaks in the plugins themselves. (Note that plugins only work on debuggable builds.) Bug: 72138063 Test: adb shell dumpsys activity service SystemUI Change-Id: I328aeb9a0940404760e9121ef26a0518371b8319
