wspoon: Support more than one group per event

Update to list groups per event along with not requiring the zone
conditions be defined for an event that should be generated for all.

Tested:
    Generated code contains events in correct conditions
    Single group event generation remains unchanged
    Two groups within event included in same generated event

Resolves openbmc/openbmc#2630
