feat(query-engine-wasm): slimmer core on wasm32 target arch

[jkomyno]

This PR contributes to https://github.com/prisma/team-orm/issues/584, and it impacts core.

It:

• reduces the amount of .clone()s
• removes some mut markers which are no longer necessary
• fixes the JSON protocol on wasm32 (similarly to how it's done already in query-engine-wasm).
