[Persisted] Fork web and native, make it synchronous on the web (#4872)

* Delete logic for legacy storage

* Delete superfluous tests

At this point these tests aren't testing anything useful, let's just get rid of them.

* Inline store.ts methods into persisted/index.ts

* Fork persisted/index.ts into index.web.ts

* Remove non-essential code and comments from both forks

* Remove async/await from web fork of persisted/index.ts

* Remove unused return

* Enforce that forked types match
