Log timings for shutdown stages

Browse Source 
Renamed BootTimingsTraceLog to TimingsTraceLog. It is now used for
 boot and shutdown logging.

Added measurements for main stages of shutdown in the system server:
ShutdownTiming: SendShutdownBroadcast took to complete: 734ms
ShutdownTiming: ShutdownActivityManager took to complete: 203ms
ShutdownTiming: ShutdownPackageManager took to complete: 17ms
ShutdownTiming: ShutdownBt took to complete: 533ms
ShutdownTiming: ShutdownRadio took to complete: 534ms
ShutdownTiming: ShutdownNfc took to complete: 1536ms
ShutdownTiming: ShutdownRadios took to complete: 1538ms
ShutdownTiming: ShutdownStorageManager took to complete: 906ms
ShutdownTiming: SystemServerShutdown took to complete: 3918ms

Bug: 64569080
Test: shutdown/reboot and check logs
