Extract the actual sending of image data from the PartialEvaluator.buildPaintImageXObject method

Browse Source 
After PRs 10727 and 11912, the code responsible for sending the decoded image data to the main-thread has now become a fair bit more involved the previously.
To reduce the amount of duplication here, the actual code responsible for sending the data is thus extracted into a new helper method instead.
