Andrew McCreight 04a47c0850 Bug 1275612 - Don't allow any origins to send objects over WebChannel. r=Gijs
The last actual Firefox user of this less-safe feature was removed in 2022.
Thunderbird's sync server still needs it, but apparently that is a prototype
that isn't really working, so they said it was okay to remove this.
