  Add the method GraphicsContext::colorSpace()

Reviewed by Simon Fraser.

colorSpace() will return the DestinationColorSpace of the underlying context for
the following cases:

1. Accelerated IOSurface based GraphicsContext
2. Unaccelerated GraphicsContext
3. CGBitmapContext based context
4. DisplayRecorder based GraphicsContext

Other types such as kCGContextTypePDF will be handled in a future patch.
