BaseTools/PatchCheck: Add copy from/to keywords

https://bugzilla.tianocore.org/show_bug.cgi?id=2044

When files are very similar, git will copy an existing
file to a new location and then apply differences.  This
is operation identified in the diff with 'copy from' and
'copy to' lines that need to be ignored.
