* types: replaced EvidenceData in block structure with EvidenceList

* types: introduced toProto, fromProto functions to EvidenceList

* updated Changelog

* Removed comments from tests

## Decription

Tag teaming with callum on debugging, wrote this to test headerHash changes from 0.34 to master. Its useful going forward as well.

## Description

- Add `context.Context` to Privval interface

This pr does not introduce context into our custom privval connection protocol because this will be removed in the next release. When this pr is released.

## Description

Separate protobuf and domain types. We should avoid using protobuf in our core logic. 

ref #5460

## Description

In protobuf `[]byte` is varint encoded. When adding txs to the block we were not taking this into account. 


Closes: #XXX

## Description

Closes: #5432

Closes #2589

evidence: modify evidence types (#5342)

light: detect light client attacks (#5344)

evidence: refactor evidence pool (#5345)

abci: application evidence prepared by evidence pool (#5354)

## Description

Check block protocol version in header validate basic. 

I tried searching for where we check the P2P protocol version but was unable to find it. When we check compatibility with a node we check we both have the same block protocol and are on the same network, but we do not check if we are on the same P2P protocol. It makes sense if there is a handshake change because we would not be able to establish a secure connection, but a p2p protocol version bump may be because of a p2p message change, which would go unnoticed until that message is sent over the wire.  Is this purposeful?

Closes: #4790

ref #5288

## Description

Remove ConflictingHeaders & compositeEvidence types


Ref #5288

adds blockstore interface to evidence and adds fix to byzantine test

Fixes #5192.

@liamsi Can you verify that the test vectors match the Rust implementation? I updated `ProofsFromByteSlices()` as well, anything else that should be updated?

ValidateBasic() for PotentialAmnesiaEvidence checks that the rounds of the two votes are different and does not check Vote Type

ValidateBasic() now also ensures that the first block is not a nil block (else the validator hasn't actually locked onto a block)

* types: reject blocks w/ ConflictingHeadersEvidence

Closes #5037

* types: reject blocks w/ PotentialAmnesiaEvidence

as well

PotentialAmnesiaEvidence does not contribute anything on its own,
therefore should not be committed on chain.

* fix lint issue

## Description

This PR removes simple prefix from all types in the crypto/merkle directory.

The two proto types `Proof` & `ProofOp` have been moved to the `proto/crypto/merkle` directory.

proto messge `Proof` was renamed to `ProofOps` and `SimpleProof` message to `Proof`.
