Add Support for serialization of mailbox backed PaintImages
For OOPR Canvas2D we need to refer to mailbox backed PaintImages in
PaintOp commands. This CL adds the SharedImageProvider interface in cc
with corresponding SharedImageProviderImpl in gpu. This class obtains
read access for each shared image and holds it until it's destroyed.
This destruction should only occur after all operations that refer to
the image have been flushed to Skia. RasterDecoderImpl handles the
creation/destruction of SharedImageProviderImpl in Begin/EndRaster
CHROMIUM respectively.
