[IOT-1958] CR 22 State Specific Property Access for /doxm Resource

[IOT-1958] CR 22 State Specific Property Access for /doxm Resource

Implementation of CR 22 feature to deny UPDATE to /doxm if any
Property in the POST representation is read-only in the current
/pstat.dos.s state.

Includes necessary update to the CBOR marshalling code to support
partial Resource representations for /doxm.

Includes updates to provisioning tools to correctly include only the
/doxm Properties being updated in the POST payload.
