Part of making the trace-dump.js code unit testable was moving it out to another
repo. This brings in all the changes made while writing unit tests, and making
the code more unit testable.
This commit adds the `--profiler-trace-path` flag. When combined with `-p` to
enable profiling, it dumps a profile as a self-contained HTML file to the given
path. The profile visualizes the traced operations as a gant-chart style
timeline.
