Add a mainline-accessible API to kill an app on sandbox death 

This API can be accessed by mainline modules to kill a specific app
process when its associated sandbox dies. It takes in the IBinder value
of the corresponding IApplicationThread of the app to kill it.

REASON_DEPENDENCY_DIED and SUBREASON_SDK_SANDBOX_DIED are used in the
emitted AppProcessDied atom.

Bug: 261558210
Test: atest SdkSandboxLifecycleHostTest
Test: m statsd && statsd_testdrive 373 emits an atom with
SUBREASON_SDK_SANDBOX_DIED
