TestRunner should always enable all the experimental features

<rdar://problem/26099748>

Reviewed by Anders Carlsson.

Source/WebKit2:

Experimental features are disabled by default, but it is
a pain to enable them in every test. Instead, have the
test runner turn them all on.

* UIProcess/API/C/WKPreferences.cpp:
(WKPreferencesEnableAllExperimentalFeatures):
* UIProcess/API/C/WKPreferencesRefPrivate.h:
* UIProcess/WebPreferences.cpp:
(WebKit::WebPreferences::enableAllExperimentalFeatures):
* UIProcess/WebPreferences.h:

Tools:

Call the new SPI that enables all the experimental features.

* WebKitTestRunner/TestController.cpp:
(WTR::TestController::resetPreferencesToConsistentValues):
