🚨 Wrap large enum variants in Box

[JMicheli]

The new version of rust comes with a new clippy lint that triggers on enums with large sizes. Enums have a size equal to their largest contained variant.

The CoreError enum came in at 144 bytes as the result of containing prisma_client_rust::QueryError, which is huge. This is easily fixed by boxing the type, which shut clippy up.

There are some other big variants still, but nothing over 100 bytes.
