Show the breakdown of each BCD item

[gsnedders]

If you look at https://web-platform-dx.github.io/web-features-explorer/features/blocking-render/, you'll see that Safari doesn't support this, though it links to https://webkit.org/b/267232 which is resolved.

https://github.com/web-platform-dx/web-features/blob/2898cf81bb72673ecf32d04089d8fa312e6287ad/features/blocking-render.yml.dist shows a number of compat features, and presumably one of these believes Safari is unsupported — but there's no easy way to know which it is.

There's no easy way online to take something like api.HTMLLinkElement.blocking and find the BCD results for them — I can guess this will be on https://developer.mozilla.org/en-US/docs/Web/API/HTMLLinkElement/blocking, and it is (showing Safari supports it).

I'd also rather not have to copy/paste every single item, guessing what MDN page might include the BCD data, till I find the one that isn't supported.

It would be nicer, and make it easier to understand why something is or isn't in Baseline, if we could see why something apparently isn't supported, for example by showing the results for each BCD item.

I guess this is actually what the comments in https://github.com/web-platform-dx/web-features/blob/2898cf81bb72673ecf32d04089d8fa312e6287ad/features/blocking-render.yml.dist are trying to communicate, I just didn't immediately process the lack of a safari: … line was meaningful.

Thanks for filing. I think it's a great idea to add something like this to the explorer. I don't have immediate ideas for what the UI could look like. It needs to be both fast and easy to pinpoint exactly what is holding a feature up, but it also needs to show everything, while not cluttering the UI.

Very open to suggestions and contributions to this. I'll also keep it in mind and try to think of ideas.
