Merge 133030 - Web Inspector: page crash when pausing in dedicated worker
https://bugs.webkit.org/show_bug.cgi?id=100837

Reviewed by Pavel Feldman.

Source/WebCore:

Pass debugger agent to InjectedScriptHost::init in case of workers.

Test: inspector-protocol/debugger-pause-dedicated-worker.html

* inspector/WorkerInspectorController.cpp:
(WebCore::WorkerInspectorController::WorkerInspectorController):

LayoutTests:

Test that Debugger.pause works for dedicated workers. The test is skipped
on all platforms that use JSC as worker debugging is not supported there
yet.

(WebInspector.dispatchMessageFromBackend):
* inspector-protocol/debugger-pause-dedicated-worker-expected.txt: Added.
* inspector-protocol/debugger-pause-dedicated-worker.html: Added.
