IndexedDB: Add IndexedDB implementation of LinkedChunk-related functions in EventCacheStore

[mgoldenberg]

Background

This pull request is part of a series of pull requests to add a full IndexedDB implementation of the EventCacheStore (see #4617, #4996, #5090, #5138, #5226, #5274, #5343, #5384). This particular pull request focuses on providing implementations for the remaining LinkedChunk-related functions in EventCacheStore.

Changes

The changes include implementations of the following functions, as well as tests for each of them.

• EventCacheStore::load_all_chunks_metadata
• EventCacheStore::load_previous_chunk
• EventCacheStore::clear_all_linked_chunks

There are also two additions to IndexeddbEventCacheStoreTransaction which support the implementation of the EventCacheStore::load_all_chunks_metadata.

• get_events_count_by_position
• get_events_count_by_chunk

Future Work

• Add remaining implementations of EventCacheStore functions without relying on MemoryStore

---

• Public API changes documented in changelogs (optional)
