Use Box for large enums

[evgenykuzyakov]

Once borsh supports Box serialization, we should switch to it: https://github.com/nearprotocol/borsh/issues/19

Enums preallocate memory for the largest item. For example the same enum (e.g. PeerMessage) contains Handshake and Block or ChunkOnePart. Handshake enum value will have the same fixed memory size as the largest item

@Rishabhraghwendra18 More work is required. I have a script, which prints all places where this issue happens.

@Rishabhraghwendra18 I started working on fixing it for near-network. https://github.com/near/nearcore/pull/5834 The issue is a bit complicated, as some other code changes / refactoring are required. I don't think it's a good issue to start with.
