feat(core): Update addEventProcessor to add to isolation scope (#10606)

Instead of to the client.
This was done to ensure this would be "global" without using the fully
global event processors (which need to be removed in a separate step).
But in the new model, it makes more sense to add them to the isolation
scope.
