media: Ensure sync token synchronization for VideoFrame images.

Instead of relying on the sync token returned by
AcceleratedStaticBitmapImage to ensure synchronization with the raster
stream used by skia, perform this when the mailbox is returned. This is
temporary to allow merging a safer change to 86 release branch.
