Event tables accessible from views

[joshua-spacetime]

Event tables were not supposed to be accessible from views but we're generating bindings for them in ViewContext and AnonymousViewContext.

- **Views.** Event tables cannot currently be accessed within view functions. Although the proposal defines clear semantics for this (event-table-ness is "infectious," meaning a view that joins on an event table itself becomes an event table), this is deferred to a future release.

I'll add that not only are they accessible, they mostly work, too. The one caveat being that the views aren't automatically recomputed so you won't get onDelete callbacks until after you do something to force the view to be recomputed. The view data seems to stick around even through running view cleanup for database events which is kind of a surprise.

I'd understand if you do something to block this until it's fully supported, but it is working well enough right now with that limitation. Doesn't work for Query/QueryBuilder views, however, as event tables lack the CanBeLookupTable trait
