Update SkiaFontWin::paintSkiaText to override typeface for HFONT

Update the SkiaFontWin::paintSkiaText method to enable the setTypeface
call regardless of the GDI_FONTS_ON_WINDOWS flag as the HFONT path is
still used by Uniscribe when GDI is disabled.

Make platform/Clock non-bizarre

No need for it to be RefCounted, so I've made create() return a PassOwnPtr
(especially bizarre was that MediaController had a PassRefPtr member).

No need for any virtual methods.

Use conventional namespacing in Clock.cpp.
