Decode CGColorSpaceRef via the WebCore::ColorSpace enum if possible.
This avoids slower CFStringRef, CFPropertyListRef encodings.

* Source/WebCore/platform/graphics/cg/ColorSpaceCG.h:
(WebCore::cachedNullableCGColorSpace):
* Source/WebKit/Shared/cf/ArgumentCodersCF.cpp:
(IPC::ArgumentCoder<CGColorSpaceRef>::encode):
(IPC::ArgumentCoder<RetainPtr<CGColorSpaceRef>>::decode):
