Function populateTransactionECDSA

Populates missing properties meant for signing using an ECDSA private key:

• Populates from using the address derived from the ECDSA private key.
• Populates nonce via provider.getTransactionCount(tx.from, "pending").
• Populates gasLimit via provider.estimateGas(tx). If tx.from is not EOA, the estimation is done with address derived from the ECDSA private key.
• Populates chainId via provider.getNetwork().
• Populates type with utils.EIP712_TX_TYPE.
• Populates value by converting to bigint if set, otherwise to 0n.
• Populates data with 0x.
• Populates customData with {factoryDeps=[], gasPerPubdata=utils.DEFAULT_GAS_PER_PUBDATA_LIMIT}.
