Shared code with prekeys rotation.
Web part should match native C++ version implemented [here](https://github.com/CommE2E/comm/blob/7c81d7e5dcda5b43f6e6fb1f631c1ae6d999e04b/native/cpp/CommonCpp/NativeModules/CommCoreModule.cpp#L632).
This code could be vulnerable to multiple promises modyfing `olm` account but fixing this is tracked in [ENG-6768](https://linear.app/comm/issue/ENG-6768/migrate-validateanduploadprekeys-to-shared-worker).
For now matching code implemented in native - but we should mark prekeys as published before uploading as described adn tracked [here](https://linear.app/comm/issue/ENG-6494/mark-prekeys-as-published-after-identity-login-registration#comment-7523423c). (cc. @varun)
