Fix Null Dereference in css_parsing_utils

This CL addresses a null pointer dereference issue within the
ConsumeColorContrast functions located in css_parsing_utils.cc.
Previously, a null dereference occurred when the code attempted to
retrieve the color provider when the document was null. To resolve
this, the updated code now includes a validation check to ensure the
document object is valid before calling the GetColorProviderForPainting
method.
