Update block schema and usages

[shuse2]

Description

1. Update current block header schema to be defined as defined in LIP. Also, remove unused schemas and types

2. move current block header property assets should be moved to block property as BlockAssets and the class should have

• fromBytes
• fromJSON
• getBytes
• sort
• getAsset (same as the current implementation)
• setAsset (same as the current implementation)
  Include BlockAssets as part of block.

3. Update storage and data access to store and get assets as part of Block. Block Assets should be stored as

[storageKey,blockID]: encodeBytesArray(assets),

where encodeBytesArray and decodeBytesArray should be defined as utils which encode/decode bytes array using schema like

arraySchema = {
  "type": "object",
  "required": ["list"],
  "properties": {
    "list": {
      "type": "array",
      "fieldNumber": 1,
      "items": {
        "dataType": "bytes"
      }
    },
  }
}

4. Update framework to use updated properties to pass build and test. (Mainly maxHeightPrevoted and maxHeightGenerated)

Acceptance Criteria

• Build and unit test should pass
• Unit test should be added for BlockAssets
• Storage integration test on lisk-chain should be added
