feat!: include state id in block signature

[lklimek]

Issue being fixed or feature implemented

With introduction of Same-Block Execution, maintaining seaparate StateID structure doesn't make sense.
We want to remove it and include into the block hash. It means we will:

• get rid of redundant information
• remove separate state id signature

What was done?

1. Removed state_id_signature.
2. Added block_id (hash of several fields from block header) to block ID.
3. Changed how block_signature is calculated
4. Refactored MaxDataBytes and related logic to reflect the fact that in same-block execution model, we know last commit size upfront.
5. Removed apphash from commits and votes, as it is indirectly included through block_id.state_id.
6. Moved VoteBlockSignBytes() to proto.Vote.SignBytes()

How Has This Been Tested?
