This is the second (and hopefully final!) change list needed to
integrate ETW into V8. In particular, we added stack-walking
functionality for JIT-ted functions!

Some notes on instrumentation:
  - The gist of getting stack-walking in ETW is we need to emit events
    with specific event IDs. These events get stitched into a pseudo-PDB
    that is recognizable by ETW.
  - Unfortunately, we cannot rely on the TraceLogging API from the first
    CL, as it does not support specifying event IDs. Instead, Bill
    Ticehurst wrote an API that peels back the TraceLogging API just
    enough so that we can specify event IDs. This API is the entirety of
    etw-metdata.h
  - We attach a CodeEventHandler that logs a stack-walking event whenever
    code movement is triggered.
