Issue TIMOB-19948: Windows: Use font cache for TextArea and Button
As of [PR 433|https://github.com/appcelerator/titanium_mobile_windows/pull/433], font cache is introduced to improve font lookup, but {{TextArea}} and {{Button}} are not using it. Make sure to use {{TitaniumWindows::UI::ViewHelper::SetFont}} for the font lookup.
