tracing: split trace event filter classes out of TraceLog

Another refactoring aimed at slimming down the TraceLog monster-class
and isolating dependencies of the tracing codebase.
This CL is a pure refactor with no intended behavioral changes.
It moves all the trace filters classes outside of the TraceLog.
This is required to make the next CLs which will change the lifetime
management of filters easier to review.
