-----------
Remove non-standard `overflowchanged`
https://bugs.webkit.org/show_bug.cgi?id=218402
rdar://71129110
Reviewed by Simon Fraser.
This landed in past 281672@main but got reverted on assumption of causing
regression on webmail.biglobe.ne.jp in 289380@main but it seems the website
claims on blog news post that it is still broken in iOS 26 [1]. So this was
not cause of regression, so this is second attempt to land this.

This patch aligns WebKit with Gecko / Firefox, Blink / Chromium by
removing non-standard `overflowchanged`.
It was removed from Blink in 2015 [2]:

https://github.com/chromium/chromium/commit/86665f61dc951e5aca388badd7b82a1691c8beb6
It was never supported by Gecko / Firefox.
