OvmfPkg/IncompatiblePciDeviceSupportDxe: Drop framework pkg dependency

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1843

This commit will drop the driver's dependency on the IntelFrameworkPkg:
gEfiLegacyBiosProtocolGuid

Such dependency has already been addressed by the duplication of the above
definition from IntelFrameworkPkg into the OvmfPkg.
