Revert Event back (from RefCountedWillBeRefCountedGarbageCollected) to RefCounted

Revert Event back (from RefCountedWillBeRefCountedGarbageCollected) to RefCounted

Moving Event to oilpan's heap caused a lot of crashes/failures. So this CL reverts Event back to RefCounted.

This CL is a revert for https://codereview.chromium.org/182063004/. However, this CL does not revert trace() methods in the original CL because there is no harm in having trace() methods in the code base. (If I revert trace() methods, I have to resolve a bunch of conflicts manually, which will be more dangerous than leaving trace() methods in the code base.)

LGTM

We want to get in a position where we can reland this soon so I see no harm in
leaving in the trace methods.
