/**
 * promiseTimeoutController is a function that returns an object with two properties: racePromiseWithTimeout and signal.
 * The main function, racePromiseWithTimeout, takes a promise and a timeout duration as parameters.
 * It returns a promise that races the original promise with a timeout.
 * If the original promise resolves or rejects before the timeout, the timeout is aborted.
 * If the timeout occurs before the original promise completes, the request is aborted.
 * The function also exposes the signal from the requestAbortController for external use.
 * @returns object with racePromiseWithTimeout and signal properties
 * @example
 * const { racePromiseWithTimeout, signal } = promiseTimeoutController()
 * const promise = fetch('https://example.com', { signal })
 * const result = await racePromiseWithTimeout(promise, 1000)
