The datasources-web-server and ee-core-profile-server layers should depend on Elytron

As foundational layers these should both use our default preferred config which is for Undertow to have an application-security-domain mapping from other to ApplicationDomain.

The `datasources-web-server` does contain this mapping but the `elytron` layer is pulled in via optional dependencies meaning it can be excluded leading to a capability resolution issue.

The `ee-core-profile-server` layer does not contain the mapping, however if users add the `elytron` layer themselves they still need to add the mapping.
