This commit will add the PCD definitions consumed by the duplicated drivers: * VideoDxe * LegacyBiosDxe into the OvmfPkg DEC file. Please note that, instead of adding these PCDs under section: [PcdsFixedAtBuild, PcdsDynamic, PcdsDynamicEx, PcdsPatchableInModule] as in IntelFrameworkModulePkg.dec file, they are added in section: [PcdsFixedAtBuild] in OvmfPkg.dec instead.
