There's a blank window bug on Windows with headless Chromium 129

There's already a ticket here: https://issues.chromium.org/issues/367755364.
(It doesn't sound like they're going to fix it, so I will.)

The simple fix is to move the window off-screen when using headless Chromium on Windows:

--window-position=-2400,-2400

chrome_options.add_argument("--window-position=-2400,-2400")

That's what I've been telling people to do on Stack Overflow:
Stack Overflow: Chrome 129 Headless shows blank window
Stack Overflow: Selenium headless broke after Chrome update

I'll apply my fix directly into SeleniumBase so that it's automatic when using headless Chromium on Windows.

I have a question: If I am using 'Driver()', how should I add 'option'?
