script: Implement QuotaExceededError WebIDL interface (#38507)

Implements the new WebIDL interface for QuotaExceededError and uses it
in appropriate places.

Testing: WPT tests. Now passing many more in
`tests/wpt/tests/WebCryptoAPI/getRandomValues.any.js` and
`tests/wpt/tests/webstorage/storage_session_setitem_quotaexceedederr.window.js`.
Fixes: #38489
