rCOMMfb78b9ed8703: [web] Add cryptoStore to shared worker

Summary

[ENG-6650 : Add cryptoStore to shared worker](https://linear.app/comm/issue/ENG-6650/add-cryptostore-to-shared-worker)

Part of the work to synchronize data between browser tabs. This diff moves the cryptoStore to the shared worker. This is hidden behind the flag for now and will be enabled after all diffs are landed.

The new worker message INITIALIZE_CRYPTO_ACCOUNT also accepts optional cryptoStore which will be used in a future migration
OLM wasm path for webworkers extracted from service worker code

NOTE: currently some parts of olm don't work in the shared worker (more info in the linked issue) but updating our fork will be handled by @kamil.

Depends on D11236

Test Plan

Made sure that olm wasm is downloaded on both dev and in docker (prod)
Tested that initializing crypto account creates and persist new accounts
Tested that if there are persisted accounts they are used instead
Tested that initialCryptoStore ovverides the existing crypto store

web/shared-worker/utils/constants.js
52 ↗	(On Diff #37930)	we should rename it, it's confusing with const
web/shared-worker/worker/worker-crypto.js
13 ↗	(On Diff #37930)
16 ↗	(On Diff #37930)	I am not sure if this is the best approach - I think the option will be to store accounts and sessions unpickled in memory to have direct and easy access to crypto operations and pickle only before persisting. What do do you think?
50–53 ↗	(On Diff #37930)	shouldn't these be read-only?

michal added a parent revision: D11324: [web] Move worker database globals to worker-database.js.Mar 14 2024, 4:15 AM

Small fixes
Keep the olm runtime objects directly in memory instead of the pickled form
Create a new separation for olm related requests in worker request types (like in the next diffs for identity client)
Use the globals getters introduced in the previous diff
