native Objective-C ffigen should test against all Apple APIs

There should be an integration test that runs ffigen against all of Apple's headers and verifies that the resulting generated file passes analysis.

Bonus points for spot-checking that some complex classes, protocols, etc. are usable.

There are 4383 headers across 255 frameworks in my Apple SDKs directory (matching /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/*.framework/Headers/**.h). When I try to generate bindings for all of them, it runs for 35min then crashes with no useful info (not sure if it's a legit bug, or if my laptop just ran out of memory or something).

So instead of pulling in all these headers as a glob, I'm going to add one framework at a time until something breaks.

There's one more bug that needs to be fixed before this can land: #1220

Tried running this test on the github CI bots in https://github.com/dart-lang/native/pull/1554. Unfortunately they don't really have enough memory to run this test without thrashing (see https://github.com/dart-lang/sdk/issues/56247). So what should be a 30sec analysis times out after 30min.

I added a randomized filter that removes 90% of the bindings, and that allows the test to complete.
