[Chromium] Add versions for WebKit-prefixed CSS properties

[queengooborg]

This PR is for the 2019 Key Result Q2 (#3710) by defining Chromium versions for WebKit-prefixed CSS properties with version_added: true. Looking through the Git repository of Chromium, I've found the following commits (collapsed for convenience) that implement the CSS properties.

Evidence of Use in 1.0

These commits show the properties being used in or before Chrome 1.0, or date far back enough.

Estimated by Date

These commits reveal a property's implementation, but for some reason cannot be tracked down in Chrome's release finder API. Their versions have been estimated based upon their date.

@vinyldarkscratch I just sent you a link to a version numbers and dates that I've compiled. It has information that is not in chrome.json etc.. In particular, pay attention to the column labeled 'Feature Freeze'. Generally, to be part of a particular release, a CL has to be merged before that versions feature freeze. There are edge cases, as there always are, but those required permission from Chrome management.

Thanks for sharing the spreadsheet with me, this will help a lot! I’ll review it once I’ve settled into my studio office. 😉

I can't confirm data on the Chromium forks. Otherwise, LGTM.
