Create Cross VM Wagmi WalletConnect Adapter

[jribbink]

WalletConnect requires special handling. Since dApps typically use a shared walletconnect connector/provider between every wallet, we need to make sure the namespaces are backward-compatible with EIP155 wallets.

To achieve this compatibility we should either:

• Declare both flow and eip155 namespaces as optional
• OR Declare flow as optional and eip155 as required (this would effectively mean mandating all FCL-WC wallets accept the eip155 namespace which is technically a breaking change to the spec but in practice Flow Wallet, as the only consumer, will not be affected)
