/**
 * Validates the provided `value` property using the `onValidate` asynchronous callback function.
 * This function returns a promise state object that tracks the status of the validation process.
 *
 * The `onValidate` callback function is expected to return a value or a promise that resolves with one of the following:
 *   - An error value indicating that validation has failed.
 *   - `undefined` if the validation succeeds without errors.
 *
 * @param props Properties according to the NEVO pattern.
 * @param onValidate Synchronous or asynchronous value validator.
 * @returns The promise state object.
