Remove RenderTheme::supportsCalendarPicker
https://bugs.webkit.org/show_bug.cgi?id=116068

Patch by Daker Fernandes Pinheiro <daker.pinheiro@openbossa.org> on 2013-05-14
Reviewed by Benjamin Poulain.

No new tests needed because it doesn't affect behaviour.

This method was never overrided by any platform
and always leaded to the same behaviour.
The code which depended on it was also removed.
