mem-ruby: Getter/setter for atomic ops in WriteMask

Adding getter and setter methods for getting and setting the atomic ops
in the WriteMask class. This allows for message types with WriteMasks to
get or set the atomic ops without explicitly modifying the constructor
for the message type. This will beused by the DMASequencer which uses the
SequencerMsg type where the constructor is auto generated via SLICC.
