FmpDevicePkg/FmpDxe: Use new Variable Lock interface

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3655
The code in FmpDevicePkg call the deprecated interface
VariableLockRequestToLockc. So I changed the code in
FmpDevicePkg using RegisterBasicVariablePolicy, instead
of the deprecated interface.
