[Web Inspector] didClearWindowObject is dispatched twice for script-less
frames
https://bugs.webkit.org/show_bug.cgi?id=318294
Reviewed by Devin Rousso.
PageRuntimeAgent forces a frame's main-world global object to be created
so script-less frames get an execution context. That creation re-enters
didClearWindowObjectInWorld, so Runtime.executionContextCreated was
dispatched twice and Page bootstrap scripts ran twice. Track the forced
dispatch on PageRuntimeAgent and skip the re-entrant one.
