feat: added CdpV2WalletProvider (EVM and Solana)

[CarsonRoscoe]

Description

Added:

• CdpV2EvmWalletProvider using @coinbase/cdp-sdk
• CdpV2SolanaWalletProvider using @coinbase/cdp-sdk
• CdpV2WalletProvider, which allows for one entry point into either wallet provider based on config
• Unified langchain-cdp-v2-chatbot using CdpV2WalletProvider, allowing you to swap networks

Notes:

• @coinbase/cdp-sdk adds a dependency on jose, which is esm only. Our unit tests run as cjs. To get passed this, we had to mock jose in the packages before any tests run.
• This jose dependency is also causing (WARN) Using hybrid module kind (Node16/18/Next) is only supported in "isolatedModules: true". Please set "isolatedModules: true" in your tsconfig.json. logs to spam in the console when running unit tests. We cannot follow its advice.

These are further justification for the dual-cjs/esm builds, while writing in esm. These logs and mocking will go away after that change.
