Re: [w3c/IndexedDB] IDBKeyRange.bound(): equal keys with an open bound should throw DataError (all engines do; 1.0 did) (Issue #510)

PRs are up:

- Spec: [[#514](https://github.com/w3c/IndexedDB/pull/514)](https://github.com/w3c/IndexedDB/pull/514)
- WPT: [[#64906](https://github.com/web-platform-tests/wpt/pull/64906)](https://github.com/web-platform-tests/wpt/pull/64906)

The spec change adds the missing equal-key/open-bound check to `bound()`. The WPT change covers the three throwing combinations plus the closed/closed success case, in window and worker globals. The new cases pass in headless Chrome 156 and Firefox 159, and Bikeshed and WPT lint are clean; WebKit wasn't tested locally. Thanks @bcardarella for reporting this.
