OvmfPkg/PciHostBridgeLib: clear PCI aperture vars for (re)init
Use ZeroMem() to initialize (or re-initialize) all fields in temporary
PCI_ROOT_BRIDGE_APERTURE variables to zero. This is not mandatory but
is helpful for future extension: when we add new fields to
PCI_ROOT_BRIDGE_APERTURE and the default value of these fields can
safely be zero, this code will not suffer from an additional
change.
