* DeviceListener: use new `getUserDeviceInfo` method
https://github.com/matrix-org/matrix-js-sdk/pull/3272 added a new
`CryptoApi.getUserDeviceInfo` method, which also works with rust crypto. Update
DeviceListener to use it, thus making many of the cypress tests work on Element
Web R.
* add missing await
... mostly to silence the quality gate
* Remove dependency on `org.matrix.e2e_cross_signing` unstable feature
Currently, we have some code that relies on the server declaring support for an
`unstable_feature` called `org.matrix.e2e_cross_signing`. There is nothing in
the spec that requires this, so this would make us incompatible with some
server implementations.
The features in question were added in spec v1.1, so we can test for that
instead.
