Make MarkData::mMarks a vector of RetainPtr<CPDF_ContentMarkItem>

It is currently a vector of CPDF_ContentMarkItem.

Copying MarkData whenever a content mark is opened or closed is
inefficient since each MarkData will have copies of the same
CPDF_ContentMarkItems.

This CL changes the vector inside MarkData to contains only pointers
to the CPDF_ContentMarkItems rather than copies of those items. More
importantly, this unifies the dictionaries of each content mark.
Previously, there were as many copies of those dictionaries as content
marks scope changes inside the mark with parameters.
