stream: Add mappable dataTypes to SPA_PARAM_BUFFERS_dataType if

Browse source 
PW_STREAM_MAP_BUFFERS is set for inputs

This lets consumer just set SPA_DATA_MemPtr as their supported dataType
and will add all by PW_STREAM_MAP_BUFFERS supported dataTypes, which
are made available with the MemPtr API to the param
