WFD: Allow WFD_SUBELEM_SET/GET all to be used with full IE buffer

Browse Source 
This extends the previously used WFD_SUBELEM_SET/GET <subelem id> design
to allow special "all" value to be used as an id to indicate that all
WFD subelements are to be set/get. This uses similar interface as was
previously added over D-Bus.
