Adding the AcTrig source options, making evr clock mode record, etc

[hongran]

In this PR, I combined a few updates: 1: Adding more options to AcTrig source. Before it was a bo record for event clock or mxc7. we made it an mbbo record to support FP1 and FP2 options. 2: Adding a record for the EVR event clock mode 3: Corrected a typo in macro U32_EventLog(N) 4: Updated a few macros like

define PulserMax 24

define OutputCMLMax 4

@hongran , for this MR I would prefer to have the different changes on different commits (e.g.: one for the fix, another for adding the actrig source options). On that way we can revert things easily on the future.

[hongran]

Yes. I will revert the branch to the version with the macro corrections only.
