Revert "media: Ensure sync token synchronization for VideoFrame images."

This reverts commit 2dc7fd65.

Reason for revert: Merged to 86. Was temporary to support merge of a safer fix.

Original change's description:
> 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.
