hg: wrap the highest layer in the `hg` script possible in trace event

This should help us have a better idea of what "interpreter startup
costs" look like. This does omit the HGUNICODEPEDANTRY block and the
LIBDIR dancing to set up sys.path, but the former is usually off and
the latter is unavoidable and should be very fast. If we get worried
about those cases we can consider open-coding the tracing logic here.
