Pass Binder token to ISuspendControlServiceInternal#enableAutosuspend

Browse Source 
The Binder token signals system_server's death to the suspend HAL,
so that autosuspend is disabled in case the framework stops or crashes
and cannot hold suspend blockers anymore.

Bug: 193776617
Test: atest SystemSuspendV1_0UnitTest SystemSuspendV1_0AidlTest
Test: Put device to sleep, observe "automatic system suspend enabled".
      On `adb shell stop`, observe "automatic system suspend disabled".
