Add SkPDFDeviceFlatenner which extends SkPDFDevice to add support to flatten the path and the text when we have perspective.
prepare to deprecate SkPDFDevice constructor, and route gm and render_pdfs to use SkDocument::Create pdf interface instead. - controlled by a flag
add comments where we are supposed to flatten other features (paint, shaders, ... )
