  Plumb an optional top SecurityOriginData into ThreadableBlobRegistry

Reviewed by Chris Dumez.

Plumb into ThreadableBlobRegistry the top SecurityOriginData associated with
the Blob URL.

For public Blob URLs, this origin is obtained from the top document. For
internal Blob URLs, the value is std::nullopt because a blob is not inherently
bound to a top origin.

This is a pre-patch for partitioning the blob registry by top origin. This
change should have any behavioral change.
