Update Long Animation Frames API data

[chrisdavidmills]

Summary

The Long Animation Frames API was release in Chrome 123, and most of it was already added to BCD. This follow-up PR specifically:

• Adds "mdn_url" fields to the PerformanceLongAnimationFrameTiming and PerformanceScriptTiming interfaces
• Updates the PerformanceScriptTiming interface's "spec_url" fields to point to the current correct spec URLs (previously they were pointing to the old locations in the Long Tasks API spec)
• Adds three missing properties to the PerformanceScriptTiming interface — sourceCharPosition, sourceFunctionName, and sourceURL.

See also https://developer.chrome.com/docs/web-platform/long-animation-frames for more details.

Whoops, I missed in my review that this didn't add sourceFunctionName as advertised in the PR description. I will file a followup PR. (Discovered this thanks to the Open Web Docs BCD Collector)
