Even after r807421 those tests are presenting some occasional flakiness in
the form of timeouts and, in a few cases, crashes in other parts of the
stack.

Clean up the code a little bit to make the code easier to follow and perhaps
reduce the chance of timeouts:

  • send_message_to_frame() does not need to be an async function.
  • Use t.add_cleanup() to a few tests to make sure any iframe we add is
    properly removed even if an error occurs.
  • Remove all calls to the assert_*() functions from both the code path used
    by initialize_generic_sensor_tests() as well as generic_sensor_mocks.js,
    so that we no longer need to include testharness.js in the iframe handler
    page.
  • Make the onmessage handler in the iframe page also send a reply when
    errors occur.

@stephenmcgruer can you force-merge this one? This is https://crbug.com/1126926 again (there's a fix in the works that should land soon).
