こんにちは TAG-さん!

I'm requesting a TAG review of {{feature}}.

Proposes a new operation, getAllRecords(), which combines [getAllKeys()](https://developer.mozilla.org/en-US/docs/Web/API/IDBObjectStore/getAllKeys) with [getAll()](https://developer.mozilla.org/en-US/docs/Web/API/IDBObjectStore/getAll) to enumerate both primary keys and values at the same time. For an [IDBIndex](https://developer.mozilla.org/en-US/docs/Web/API/IDBIndex), getAllRecords() also provides the record's index key in addition to the primary key and value. Lastly, getAllRecords() offers a new direction option to enumerate records sorted by key in descending order.  To add the direction option to the existing getAll() and getAllKeys() operations, this explainer proposes new function overloads that accept the same argument as getAllRecords(): the IDBGetAllOptions dictionary.
