This patch turns on INPUT_TYPE_COLOR and implements it using the native
Mac color panel.

No new tests added.

Currently, there are no automated ways to test the types of changes made in this patch. (i.e. checking
which color is being displayed in the color panel, checking which color element is currently
associated to the color panel, checking the state of color elements after directing away and
being directed back to its page, etc.)

* Configurations/FeatureDefines.xcconfig: Enabled INPUT_TYPE_COLOR.
* WebCore.exp.in:
* WebCore.xcodeproj/project.pbxproj:

* html/ColorInputType.cpp:
(WebCore::ColorInputType::handleDOMActivateEvent): Reattaches the color picker if
  a color picker has already been shown for an element
(WebCore::ColorInputType::shouldResetOnDocumentActivation): Always returns true, needed to
  detach the color picker when caching a page.
* html/ColorInputType.h:

* html/HTMLInputElement.cpp:
(WebCore::HTMLInputElement::documentDidResumeFromPageCache): For <input type='color'>,
  don't reset the element.
(WebCore::HTMLInputElement::documentWillSuspendForPageCache): For <input type='color'>, call detach().
* html/HTMLInputElement.h:

* platform/ColorChooser.h:
