Display JavaScript builtins

[ascorbic]

Describe the feature

We are testing and tracking support for JS builtins, but we're not surrently displaying them on the site. It may be a bit harder to display because the features are often nested more deeply than the single level that the web APIs have

Additional information

For built-in objects, it would be useful to be able to show how well each runtime supports the latest standards, starting with the newest standard.

I don't think it would make much sense to show even older standards, such as those supported by most runtimes.
Even if we support even those displays, the priority should be low.

For example:

ES2024

• ArrayBuffer.resizable
• Atomics.waitAsync
• Map.groupBy
• Object.groupBy
• Promise.withResolvers
• String.isWellFormed
• String.toWellFormed

ES2023

• Array.findLast
• Array.findLastIndex
• etc...
