Standardize copyright year (#3737)
Standardizes all first-party copyrights on a single year, as is done in flutter/flutter and flutter/engine. All code now uses 2013, which is the earliest year that was in any existing copyright notice.
The script checks now enforce the exact format of first-party licenses and copyrights.
Fixes flutter/flutter#78448
