Box inside BeaconChainError #7473
Description
In the interest of unblocking CI I opened a PR here with some clippy lint fixes for rustc 1.87. Clippy is complaining that BeaconChainError is too large, so I made the quick fix by boxing the enum in several places. It would be cleaner to find which variants inside BeaconChainError are too large and box those instead of boxing the parent enum.
