[Paris] Implement stake, unstake & finalize_unstake pseudo operations in the Wallet API

[dsawali]

This ticket is a follow up to the Contract API counterpart: #2886

Wallet API support

• staker related:
  • stake
  • unstake
  • finalize_unstake
• baker related:
  • set_delegate_parameters

Note:

• The endpoint GET - /chains/main/blocks/head/context/adaptive_issuance_launch_cycle can be used as a heuristic to check whether Adaptive Issuance is enabled in the protocol - [Paris] new adaptive issuance rpc endpoints (generic) #2678
  it returns the cycle it started (i.e.6) need to compare it with the head block .metadata.level_info.cycle to confirm it started

Protocol Oxford will bring forth a feature flag, that when enabled, will allow users to perform stake, unstake, and finalize_unstake pseudo operations on implicit accounts.

Support the 3 pseudo operations in Taquito wallet API.

Implementation Details

Stake, unstake, and finalize_unstake are all considered 'pseudo operations' because they are essentially an extension of the existing transaction operation.

Refer to this document for further details on what that means: https://hackmd.io/@dsawali/H1_vK4t33

Implement a method wrapper in wallet API similar to increasePaidStorage, etc.

The method wrappers should be callable via the Wallet API as such:

await Tezos.wallet.stake(...);

await Tezos.wallet.unstake(...);

await Tezos.wallet.finalizeUnstake(...);

Testing

Write appropriate unit and integration tests. This will be part of the ticket's acceptance criteria.
