Add setters to export symbols.

* Source/autotools/symbols.filter:

Source/WebCore:

Start generating the code for settings that call m_page->setNeedsRecalcStyleInAllFrames()
when the value is changed. This allows us to generate 10 more settings. As a follow up, we
can remove some methods from DRT/WTR after this.

No new tests, this is a build refactor and should not impact any test results.

* page/Settings.cpp:
(WebCore::Settings::Settings): Remove member variables. Add SETTINGS_SETTER_BODIES macro that
has the generated setter bodies.
* page/Settings.h:
(Settings): Remove code that is now generated.
* page/Settings.in: Add new entries with setNeedsStyleRecalcWhenSetting=1
* page/make_settings.pl:
(defaultItemFactory): Add setNeedsStyleRecalcWhenSetting flag.
(generateSettingsMacrosHeader): Print macro for setter bodies.
(printConditionalMacros): Add setter body code.
(printGettersAndSetters): Pass in setNeedsStyleRecalcWhenSetting so we know whether to inline the
setter in the header or not.
(printGetterAndSetter): Ditto.
(printSetterBodies): Print macro for setter bodies.
(printSetterBody): Print setter body for a single setting.
