Introducing the following GRUB commands to manage the certificates.
1. append_list_db:
Show the list of trusted certificates from the db list
2. append_add_db_cert:
Add the trusted certificate to the db list
3. append_add_dbx_cert:
Add the distrusted certificate to the dbx list
4. append_verify:
Verify the signed file using db list
Note that if signature verification (check_appended_signatures) is set to yes,
the append_add_db_cert and append_add_dbx_cert commands only accept the file
‘X509_certificate’ that is signed with an appended signature.
