Automatic update from web-platform-tests
[IndexedDB Storage Partition] (20) Add more 3P API tests

We should verify the full IDB surface area inside an iframe, but for
now a single test with an assortment of verifications is sufficient
to test third party storage partitioning didn't break anything.

This CL is a part of a series:
(1) Tentative WPT
(2) Add to third-party-storage-partitioning virtual suite
(3) Add WPT to check for persistence
(4) Rename IndexedDBBucketState(Handle)
(5) Store BucketLocator to IndexedDBCallbacks and DatabaseImpl
(6) Store BucketLocator to CursorImpl and TransactionImpl
(7) Store BucketLocator to IndexedDBDatabase
(8) Store BucketLocator to IndexedDBBackingStore and IndexedDBCursor
(9) Store BucketLocator to IndexedDBBucketState and IndexedDBFactoryImpl
(10) Store BucketLocator to IndexedDBContextImpl
(11) Cleanup inside IndexedDB
(12) Propagate BucketLocator to IndexedDBObserver
(13) Propagate BucketLocator to IndexedDBControl
(14) Move mojom to privileged folder
(15) Split base data path out
(16) QuotaManager::GetBucketById
(17) Migrate third party storage to non-origin buckets
(18) Purge buckets by origin and top site
(19) Run all WPT against ThirdPartyStoragePartitioning
(20) Add more 3P API tests
