TraceProcessor: introduce RefCounted<T>, remove std::shared_ptr
1. There is already a case of manually-handled refcounting
in TraceBlob / TraceBlobView.
2. PacketSequenceStateGeneration was using std::shared_ptr.
That introduce unnecessary atomics because it's thread-safe
(which we don't need and it's a fast-path).
