Support a range of major and minor version.
In DeltaPerformer we set a supported major and minor version and only
accept that perticular version, but in reality we still support older
versions to test backward comatibility.
This CL change the supported major and minor version to a range to
reflect the truth of which version is supported and moved them to
payload_constants.
This is also useful when we have multi payload and want to reuse old
payload for non system partition while updating the system partition
to use a higher minor version.
