This reverts commit 0a0304c426.
Reason for revert: Breaking metal
Original change's description:
> Add experimental API to draw a set of SkImages in one SkCanvas call.
>
> The client provides a src and dst rect for each image as well as
> a bitfield that indicates whether each edge of the image should be
> antialiased. This per-edge AA is useful for tiled compositors.
>
> Rather than take a full SkPaint this API only takes an alpha, a filter
> quality (which is pinned to kLow), and a blend mode. This is a likely
> point of future evolution.
>
> Currently the API is only fully implemented for kSrcOver on the GPU
> backend. With other blend modes or on other backends AA will be ignored
> for images that do not have all four edge AA flags set.
>
> BUG: skia:8444
