Web Inspector: [Overrides] Add ability to override the page CSS media type
https://bugs.webkit.org/show_bug.cgi?id=103752

Reviewed by Pavel Feldman.

Source/WebCore:

This change emulates the CSS media types through the instrumentation of FrameView::mediaType().
Even though it already checks the associated FrameLoaderClient::overrideMediaType(), instrumenting
every single platform FrameLoaderClient implementation out there seems wrong.

Test: inspector/styles/media-emulation.html

* English.lproj/localizedStrings.js:
* inspector/Inspector.json: Add Page.setEmulatedMedia().
* inspector/InspectorInstrumentation.cpp:
(WebCore::InspectorInstrumentation::applyEmulatedMediaImpl): Added.
* inspector/InspectorInstrumentation.h:
(WebCore::InspectorInstrumentation::applyEmulatedMedia): Added.
* inspector/InspectorPageAgent.cpp:
(WebCore::InspectorPageAgent::restore): Restores the media emulation state.
(WebCore::InspectorPageAgent::disable): Resets the media emulation state.
(WebCore::InspectorPageAgent::setEmulatedMedia): Added.
(WebCore::InspectorPageAgent::applyEmulatedMedia): Applies the emulated CSS media if needed.
* inspector/InspectorPageAgent.h:
* inspector/front-end/CSSStyleModel.js: Add the list of media types.
* inspector/front-end/OverridesView.js: Add the CSS media type override UI.
(WebInspector.OverridesView):
(WebInspector.OverridesView.prototype._createMediaEmulationElement): Builds the UI.
(WebInspector.OverridesView.prototype._emulateMediaChanged): Handles the control value changes.
* inspector/front-end/Settings.js: Add the "emulatedCSSMedia" setting.
* page/FrameView.cpp:
(WebCore::FrameView::mediaType):
  Uses InspectorInstrumentation::applyEmulatedMedia() to provide the emulated value.

LayoutTests:

The test invokes PageAgent.setEmulatedMedia() and emits the WebInspector.cssModel.mediaQueryResultChanged() signal.

* inspector/styles/media-emulation-expected.txt: Added.
* inspector/styles/media-emulation.html: Added.
