Summary

• Modify Solana Vault swaps logic such that native sol vault swaps are immediately fetch-and-closed account while for other sol assets, old functionality remains where we wait for the batch to fill or wait for timeout before we initate account closures.
• Update to new Swap Endpoint program from PR: https://github.com/chainflip-io/chainflip-sol-contracts/pull/81
• Add the fetching native Solana Vault swaps instruction as part of the close_accounts transaction.
• Use the same number of nonces requirement for Vault swap fetches and deposit channel fetches.
