Reviewed by Chris Dumez.

Ensure that experimental features (which are generally off by default) are truly off in Lockdown Mode.
This is meant to protect users that might have an experimental feature on for development work,
who would not want that feature active for Lockdown Mode.

* Source/WebCore/Scripts/GenerateSettings.rb: Add new generators to set turn off all unstable features.
* Source/WebCore/Scripts/SettingsTemplates/Settings.cpp.erb: Ditto.
* Source/WebCore/Scripts/SettingsTemplates/Settings.h.erb: Ditto.
* Source/WebKit/WebProcess/WebPage/WebPage.cpp:
(WebKit::adjustSettingsForLockdownMode): Ensure that all unstable features are off.
* Tools/TestWebKitAPI/Tests/WebKitCocoa/ProcessSwapOnNavigation.mm: Add tests.
