/**
 * Calculate the input gas cost for calldata according to EIP-7623.
 *
 * EIP-7623 introduces a floor cost for calldata to prevent abuse for data availability.
 * The gas cost is the maximum of:
 * 1. Standard cost: 4 gas per zero byte + 16 gas per non-zero byte
 * 2. Floor cost: 10 gas per token (where tokens = zero_bytes + nonzero_bytes * 4)
 *
 * This function only calculates the calldata portion - execution gas and base costs
 * are handled elsewhere in the transaction gas calculation.
 *
 * @param input - The calldata bytes
 * @returns The gas cost for the calldata portion
