Expose public interface to starting and stopping IME tracing
The added interface makes it possible to start or stop IME tracing from
another process. This will be used together with the DevelopmentTiles to
ghather IME tracing data when the WinscopeTrace tile is used.
Bug: 154348613
Test: flash a device together with the other change in this topic
enable the WinscopeTrace tile and do some actions
disable the WinscopeTrace tile
do a bugreport and visualise contents in Winscope
or just check contents of /data/misc/wmtrace/ through adb
