2025-03-04hw/uefi: add var-service-auth.cGerd Hoffmann1-0/+361
This implements authenticated variable handling (see AuthVariableLib in edk2). The by far most common use case for auth variables is secure boot. The secure boot certificate databases ('PK', 'KEK', 'db' and 'dbx') are authenticated variables, with update rules being specified in the UEFI specification.
