OvmfPkg: non-null PcdLib instance for the CSM VideoDxe

VideoDxe is a UEFI_DRIVER, so it has by default a null instance
of PcdLib.  It accesses two PCDs that are now dynamic
(gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution
and gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution).
Similar to r15362 (OvmfPkg: non-null PcdLib instance for
GraphicsConsoleDxe, 2014-03-22), we need to specify a non-null
instance of PcdLib.

This patch unbreaks the CSM VideoDxe module for OvmfPkg.
