We used a whitelist to determine which atoms should have their timestamps truncated to the nearest 5 minutes. This changes the logic to a blacklist so that we can get fine grained timestamps from vendor and mainline atoms. Also reserves a range for atoms that need to be truncated in the future. Bug: 134574701 Test: inspected generated statslog.cpp file to make sure it had the correct blacklist Test: testdrive on ScreenStateChanged to ensure timestamps are preserved when they should be Test: testdrive on CallStateChanged to ensure timestamps are truncated when they should be.
