Vlv2TbltDevicePkg/AcpiPlatform: Add variable protocols to depex

Add the arch protocols gEfiVariableArchProtocolGuid and
gEfiVariableWriteArchProtocolGuid to the dependency expression
for the AcpiPlatform module to guarantee that the variables
that AcpiPlatform depends upon are set before they are used by
this module.
