Reland of: Revise the code for premultiplyAlpha=false for createImageBitmap(HTMLCanvasElement)

It turns out that HTMLCanvasElement is always premultiplied in Blink, so
we cannot simply use a decoder to re-decode it to a un-premultiplied format.
The strategy this CL takes is that after cropping the HTMLCanvasElement
into a SkImage, we convert the SkImage into a un-premultiplied format if
that's what the option specifies.

PS#1 causes compilation error, PS#4 should work.
