Description Charlie Wolfe 2024-05-05 18:18:48 PDT 
We were adding null security origins for out-of-process frames in `WebLoaderStrategy::scheduleLoadFromNetworkProcess`, which caused the network process to crash when trying to convert them to a string. Instead, use opaque origins and change `frameAncestorOrigins` to hold Ref, as it can no longer be null.
