This function adds a timed action to the timed action queue. It writes a value to an address at a specified system time. An optional mask can be applied so that only those bits are changed.
The action types are WRITE_ACTION, RMW_ACTION. WRITE_ACTION writes the value to the address. RMW_ACTION reads the values at the address and modifies the bits specified by the mask and value.
