Creates an Unsigned Transaction for Splitting a Solana Stake Account

Supports both standard recent blockhash nonces (default) and durable nonces (more information here):

• For standard recent blockhash nonces, leave nonce_account and nonce_authority empty.
• For durable nonces, define a nonce_account.
