Subject: OvmfPkg: Add PCD for Host Bridge dev. ID (PcdOvmfHostBridgePciDevId)

Set from PEI, this PCD allows subsequent stages (specifically
DXE_DRIVER and DXE_RUNTIME_DRIVER) to infer the underlying platform
type (e.g. PIIX4 or Q35/MCH) without the need to further query the
Host Bridge for its Device ID.
