Mono.Cairo: Add Context.SetSourceColor(Color) convenience method

The Color property was obsoleted, but the suggested replacement
SetSourceRGBA has 4 double parameters, which can be unconvenient.

Add a SetSourceColor that takes a Cairo.Color parameter, make the Color
property use it, and update the message on the Obsolete attribute.
