Reviewed by Anders Carlsson.

Shadow DOM is not an experimental feature. We want
it enabled by default.

This fixes the timeout in:
WebKit2.InjectedBundleMakeAllShadowRootOpenTest

* Shared/WebPreferencesDefinitions.h: Move the Shadow
DOM preference out of Experimental.
* WebProcess/InjectedBundle/InjectedBundle.cpp:
(WebKit::InjectedBundle::overrideBoolPreferenceForTestRunner):
* WebProcess/WebPage/WebPage.cpp:
(WebKit::WebPage::updatePreferences):
