feat: StorageEstimateUsageDetails

[lekoaf]

This PR adds usageDetails to StorageEstimate with its own interface StorageEstimateUsageDetails.

This is already supported in Chrome and discussions are being had about this at WhatWG.

Try this in Chrome:

const quota = await navigator.storage.estimate()
console.log(quota)

{
  quota: 74378659430,
  usage: 385967396,
  usageDetails: {
    caches: 335832064,
    indexedDB: 50090672,
    serviceWorkerRegistrations: 44660
  }
}

I added [key: string]: number because I'm not sure what other keys can be in the usageDetails object.

Should I also update webworker.generated.d.ts?

Thanks for helping.
Is this a change in the widl from upstream?
I suspect no, so the correct place would be the addTypes.json

[lekoaf]

Thanks @HolgerJeromin. I'll see what I can come up with. 🙈

The PR has no activity, and a single engine support only from Blink doesn't meet the standard to be added. It will be automatically added when it gets multiple engine supports.
