Remove duplication of encoded image data

Now there are at least two encoded image data: one is in Image/ImageResource as
SharedBuffer and the other is in DeferredImageDecoder as SkRWBuffer. This CL
removes former when possible (non-icon bitmaps), and generate the SharedBuffer
from the SkRWBuffer if needed.

Simplify the condition for destroyDecodedData()

This CL simplifies the condition for destroyDecodedData(). When an error
occurs, |m_image| must be null and the condition for |m_image| doesn't
make sense.

This CL also fixes another if condition and inserts DCHECK based on the
above assumption.

ImageResource: Reset the encoded image size after receiving all data

Before this CL, an ImageResource's encoded image size remains non-zero
even after the encoded data is cleared. This CL fixes this to make
Resource::onMemoryDump report more accurate size.
