Feat: support multi wallet connector

[RetricSu]

this pr supports multiple wallet connectors via using web3-react lib. For injected webview environment (eg: Metamask/ImToken/SafePal), the connector use Metamask connector, we only add different icons to better identify the wallet, same as Yokai Swap.

---

some todos before merging this pr:

• try wallet-connect with a mobile wallet to see if the process is normal
• check if the previous provider used in light-godwoken library is compatible with new wallet connector providers.

Testing

I've tested for a round or two, here's the connection test results for the newly added wallets.
Testing process:

1. Connect to wallet
2. Add and switch to testnet network
3. Deposit capacity to L2

imToken

No issues found

WalletConnect (MetaMask&imToken):

1. Cannot get L2 balance

Safepal

1. First time visiting the page, godwoken-bridge is already connected without asking
2. Safepal doesn't support adding networks, and testnet is not in Safepal's built-in networks
3. L2 balance is always 0
4. Close and reopen Safepal, godwoken-bridge is now disconnected for no reason (tested for more round, it is not always disconnected when reopening the app), and when clicked "Connect" button and selected "Safepal", the modal closes and nothing else happens
