platform/rd1ae: Enable pointer access protocal
Enabled the pointer access protocal on rd1ae platform by reducing the
threshold value `COMMS_MHU_MSG_SIZE`. The RSE messages with payload data
size larger than the value will be serialized with the pointer access
protocol.
Configured the carveout region for the pointer access protocal.
Added the rd1ae-opteesp deployment to the b-test list.
