Add Safari versions for IDB* API

[queengooborg]

This PR adds real values for Safari (Desktop and iOS/iPadOS) for the IDB* API, based upon results from the mdn-bcd-collector project (v3.1.4).

Tests Used: https://mdn-bcd-collector.appspot.com/tests/api/IDB*

@vinyldarkscratch there are conflicts now, I'll hold off with review until pinged.

[queengooborg]

@foolip Ping!

[foolip]

With all the batch changes I asked more annoying questions about anything that didn't fit the pattern :)

[foolip]

This is openKeyCursor and is later than the rest. Is this based on mdn-bcd-collector results?

[queengooborg]

Yeah, this is pretty much all from the collector results, aside from ensuring iOS stays marked as "8" and not earlier.

[foolip]

This doesn't match https://developer.mozilla.org/en-US/docs/Web/API/IDBIndex/openKeyCursor, can you check if the data for that is also wrong?

[foolip]

OK, I've compared https://mdn-bcd-collector.appspot.com/tests/api/IDBObjectStore and https://mdn-bcd-collector.appspot.com/tests/api/IDBIndex in Safari 10 and 10.1, and there's a lot more than this that came in 10.1.

How about backing this out and making all of those changes as a single PR? I'm not sure I understand why the collector isn't updating all of the data, but it looks like api.IDBIndex.openKeyCursor was in Safari 8 and just temporarily gone. Something weird happened at any rate, which is better to split out.

[foolip]

This is objectStoreNames, confirmed manually?

[foolip]

Let's back this out too, I'm no longer trusting of the 10.1 versions.

[foolip]

I've confirmed with some npm run traverse safari_ios api $version calls that there's no iOS data <8 now.

[foolip]

Hmm, now I'm having second thoughts in light of #9423, where we're contemplating just removing 6.1 and 6.2 as releases. If we do, we'd change these 6.1 back to 7 again.

So... uh... merge away, regret it later think some more.

[foolip]

OK, so final deal. I sent #11145 and think we should go with the 6.1→7 rewrite in #9423 (comment).

Can you back out all the 7→6.1 changes here?

[foolip]

This all also matches the api.WindowOrWorkerGlobalScope.indexedDB.worker_support entry:

browser-compat-data/api/WindowOrWorkerGlobalScope.json

Lines 901 to 906 in fa9e3ca

@vinyldarkscratch this is now only blocked on backing out some 10.1 / 10.3 versions that seems complicated.
