MdeModulePkg/Variable/RuntimeDxe: Restore Variable Lock Protocol behavior
https://bugzilla.tianocore.org/show_bug.cgi?id=3111
The VariableLock shim currently fails if called twice because the
underlying Variable Policy engine returns an error if a policy is set
on an existing variable.
This breaks existing code which expect it to silently pass if a variable
is locked multiple times (because it should "be locked").
Refactor the shim to confirm that the variable is indeed locked and then
change the error to EFI_SUCCESS and generate a DEBUG_ERROR message so
the duplicate lock can be reported in a debug log and removed.
