tp: extract out tokenizing logic from ProtoTraceTokenizer

This CL does three things:
1. Renames ProtoTraceTokenizer -> ProtoTraceReader to better reflect its
   true purpose.
2. Extracts out all the actual tokenization from ProtoTraceReader into a
   new ProtoTraceTokenizer class which can be reused. This includes
   handling any decompression of compressed packets.
3. Updates all usage of ProtoTraceTokenizer to ProtoTraceReader.

This is needed to support handling gzip traces in DecompressTrace
without duplicating really subtle logic.
