Implementing the following host functions according to the design proposed in [NEP-364](https://github.com/near/NEPs/pull/364) ```rs pub fn ed25519_verify( &mut self, sig_len: u64, sig_ptr: u64, msg_len: u64, msg_ptr: u64, pub_key_len: u64, pub_key_ptr: u64,...

NEP-384: implementation

keep track of latest_block_hashes on Chain struct

logic: improve test coverage and error messages of ed25519_verify

[crypto+move] add support for Blake2b-256 in Move

8

Taken a lot of inspiration from https://github.com/aptos-labs/aptos-core/pull/4181#issue-1372293035 ### Description Add BLAKE2B-256 hashing in Move, to support folks writing bridge contracts to other platforms, as per conversations with @JoshLind and @alinush....

- assemble input for prover over a finalized block - get the prover result - send the packet to the other chain with the proof

fix finding `6. Finality proof verification is too strict`

1. Cherry-pick pallets from runtime metadata 2. reconnect on timeout of stream 3. avoid having to use low level future/stream primitives
