Context: https://crrev.com/c/3582395 (whole feature)

This CL adds the first batch of inspector tests for the upcoming
"Restart frame" feature. Landing the tests upfront allows us to
better discuss the proposed API as well as think early about
corner cases we should test.

The tests check for the functionality of `Debugger.restartFrame`, as
well as the newly added parameter `canBeRestarted` in
the `Debugger.paused` event.
