Framework bump rm event def - #111

LDMX-Software/ldmx-sw#1251 for context.

Refactoring of the dictionary building infrastructure removed the EventDef.h header. This PR just removes that header and includes the specific event objects needed for the processors instead.

In addition, I remove the RootSimFromEcalSP generator for the following reasons. In general, I think it would be better to start from scratch, perhaps with a modification to the ReSimulator rather than using a generator with the plain simulator.

• It uses the EventFile::close function which has been removed from Framework in favor of a close-on-destruct method.
• It has not been used (to my knowledge) in years, so even if it was compile-time patched, I'm unsure if it is functional.
  • The logic within this generator is a bit suspicious to me, I am unsure if it is getting all of the particles leaving the ECal and/or if it is using the same particle multiple times.
• The updated re-simulation infrastructure accomodates this by allowing users to choose which events to re-simulate and update the HCal geometry such that the changed geometry will see the same events that were interesting in previous geometries.
