verification/rvgen: Adapt dot2k and templates after refactoring da_monitor.h

Previous changes refactored the da_monitor header file to avoid using
macros. This implies a few changes in how to import and use da_monitor
helpers:

 DECLARE_DA_MON_<TYPE>(name, type) is substituted by
 #define RV_MON_TYPE RV_MON_<TYPE>

Update the rvgen templates to reflect the changes.
