Browser-compat-data: Update WebKit vendor-prefixed properties using data from the Apple documentation

[connorshea]

I'm not sure if this is worth the trouble, but I found this list (archive.org link just in case) of vendor-prefixed CSS properties in Apple's WebKit documentation that lists what versions of Safari they started supporting each given prefix in.

A lot of the data files in this repo, e.g. animation.json (see below), don't list the specific version where the vendor prefix was introduced, but this data _can_ be found in the Apple documentation. It might be useful to look through these and try to fill in the blanks.

Got that list scrubbed down to just the statements that mention when the property's available in Safari, so that it can be turned into a PR -- which I will definitely tackle once I get a little more rest!

This has seen many PRs which have been merged. Is that all that is needed here or do we have more material in the Apple docs?

From what I can tell, we got everything!
