Enable cypress tests for shields with rust crypto (#11589)

* Use new crypto-api for cross user verification

* update verification flow with new APIs

* Replace some calls to `checkUserTrust`

A start on https://github.com/vector-im/crypto-internal/issues/147

* Enable cypress tests

* update tests

* Delegate decisions on event shields to the js-sdk

* rerender after editing events

This is required because a transition from "valid event" to "unencrypted event"
no longer triggers a state change, so the component does not render
itself. Previously, this would be a transition from `verified:
E2EState.Normal` to `verified: null`.

* Update tests

* prettier

* Test coverage

* Enable cypress tests for shields with rust crypto
