indexeddb: Implement openCursor and openKeyCursor for object store (#39080)

Browse source 
Continue on implementing indexeddb's cursor.

This patch focuses on implementing the `openCursor` [1] and
`openKeyCursor` [2] methods of the `IDBObjectStore` interface, which
create and initialize cursors by running the iterate-a-cursor algorithm
[3].

It also adds struct `IndexedDBRecord` to
`components/shared/net/indexeddb_thread.rs`. This struct can later be
used to implement the new `IDBRecord` interface [4].

Testing: Pass WPT tests that were expected to fail.
Fixes: Part of #38111
