Add WKWebView to BCD

[queengooborg]

This PR adds WKWebView to BCD, which fixes #23296. The data will be set to mirror for all features at first, which will occur in a follow-up PR.

I'm a bit confused about version. My iPad with iOS 17.5.1 reports version 605.1.15 as you can see in openwebdocs/mdn-bcd-results#1164. This does not really map out to the engine versions for Safari here.

[queengooborg]

That's because the user agent string was frozen at that time, so it always reports WebKit "605" now, despite it being a much newer version of WebKit. This is the case for Safari Desktop and Safari iOS too.

This looks good to me. However, prior to adding this, I would like to know how many values we would record that aren't "mirror". Do we have a collector run to assess that?

[queengooborg]

Here's a file that contains the changes made by update-bcd, with some cleanup work: WKWebView.patch

[Elchi3]

Thanks @queengooborg!!

This get us 179 features that are not supported webview_ios but are supported in safari_ios.

Do we know if these findings are correct? @NiklasMerz @RupertBenWiser @jdatapple

If so, I think I'm fine with proceeding to add webview_ios to BCD.

Output of npm run traverse -- -b webview_ios -f nonmirror on this branch after running the migration script and applying @queengooborg patch from the collector run.

Given I don't have experience in WKWebView, I just created an emulator on my macbook and verified that the results you flagged were not supported in an emulator, but were in safari.

The only issue I flagged was that on my ios 17.5.1 device, api.DeviceMotionEventAcceleration, DeviceMotionEventRotationRate, Navigator.clearAppBadge, and Navigator.setAppBadge were also not supported in safari. That seems like an issue with the larger data set though so no concerns regarding this list.

Would love to hopefully get @jdatapple 's eyes on this before landing.

[Elchi3]

Let's do this! Given we are able to maintain this data using the OWD collector and BCD already has the android webview data, too, it seems reasonable to also maintain webview_ios data. The 179 features that are not supported webview_ios but are supported in safari_ios are particularly interesting to caniwebview.com and other consumers.

After this PR lands, I expect to see a PR that runs the migration and a collector run for webview_ios.
