[1.3] RVC Clean Mode Cluster XML has to be updated as per spec

[Ashwinigrl]

Description:

• "OnMode" is OnOff Feature dependent attribute. This feature is marked as X in conformance. (X means - This is disallowed for the cluster derivation), but it is reflecting in XML file.

This spec indicates that the RVC device type that uses the RVCCleanMode cluster does not support the OnOff feature. However it doesn't say anything about the RVCCleanMode cluster itself. Technically this cluster can be used again and that feature could be enabled.

I agree that it is unlikely that another device should want to use this cluster. But to remove this attribute from the RVCCleanMode cluster, we should first update the spec for the cluster. Similar to what was done for the StartUpMode attribute here. This might introduce some backwards compatibility concerns.
