Fri Aug 13 11:45:06 UTC 2021
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3562
Create new command line option to have VfrCompile generate
a Json format file that contains the EFI Variable related
information including:
1. The C struct associate the EFI variable
2. The variable vendor Guid, name and attribute
3. The variable field's default value
