check_copyright: Exclude moved files from checks
Created by: nicola-mazzucato-arm
Files that are moved from one directory into another with 100% similarity should be excluded from the copyright check, in other words, they should not need an updated copyright year.
Add a new git operation and introduce a further comparison for files that are simply moved across directories to be excluded from the copyright check in the loop.
