[unseasoned-pdf] Create a new PaintReadyRect constructor.

To migrate DoPaint() to PdfViewPluginBase in the future, a common
PaintReadyRect constructor that works for both Pepper and non-Pepper
plugins is needed.

Since Image can be created from either SkBitmap or pp::ImageData, this
CL creates a PaintReadyRect constructor that takes an Image as input,
and replaces the existing PaintReadyRect constructors with it.

This CL also cleans up some unused forward declaration and headers in
the modified files.
