Event Lineage: Create Transform Function for All Filter

[Cali0707]

Problem
Transform functions are how we track changes to eventtypes as events flow through the system. To support the all filter, we should implement a transform function to represent how a given eventtype becomes "narrower" as it passes the filter. Specifically, this transform function should (for each filter in the all filter):

1. Apply the filter
2. If the resulting eventtype is nil, return nil.
