2756: feat(hardfork): ckb2021 hardfork features (vm related part) r=doitian,quake a=yangby-cryptape

### Changes

- New hardfork Features

  -  [CKB-RFCs PR 236: RFC: ckb vm version1 changes](nervosnetwork/rfcs#236)

  -  [CKB-RFCs PR 237: RFC: vm syscalls 2](nervosnetwork/rfcs#237)

  -  [CKB-RFCs PR 238: CKB VM version selection](nervosnetwork/rfcs#238)

- All changes are followed to the latest RFCs, except:

  - Add a "edition" field to all configuration files: CKB chain specification or app configurations.

#### CKB Chain Edition

- If no `edition` field, the default edition is `"2019"`.

-  After this PR, the default files created by `ckb init` will be edition `"2021"` files.

   But the public chains will still use the edition `"2019"` CKB chain specification as the built-in spec.

   At present, there are only to public chains: "mainnet" and "testnet".

- The edition `"2019"` doesn't support hardfork parameters.

- How to upgrade from edition `"2019"` to `"2021"`?

  Modify your spec file (default is `specs/dev.toml`), `ckb.toml` and `ckb-miner.toml`:

    - Update all `hash_type = "data"` to `hash_type.kind = "data"` and `hash_type.vm_version = 0`.

    - Update all `hash_type = "type"` to `hash_type.kind = "type"`.

    - Insert `edition = "2021"` into the head of the files.

  After upgrade the edition of chain specification,  the first time to run the CKB, you have to use `--overwrite-spec` parameter. The details of this parameter can be found with `ckb run --help`.

### BREAKING CHANGES

- The field `hash_type` in `Script` is changed from a `String` to an `Object` for all JSON RPC methods.

  The details can be found in the latest RFCs.

- The argument `--ba-hash-type` for `ckb init` is split into two arguments: `--ba-hash-type-kind` and `--ba-hash-type-vm-version`.

  More details can be found with `ckb-release init --help`.
