Issue #3589272: Replace deprecated DomainAccessManager and DomainNegotiator calls; require domain ^3.1

Frank Mablyrequested to merge
issue/domain_extras-3589272:3589272-domain-3.1-api into 3.x

Issue: https://www.drupal.org/project/domain_extras/issues/3589272

Replaces the deprecated DomainAccessManager::getAccessValues() call in domain_access_linkit production code with DomainAccessFields::getAccessValues(), and updates three test files to use DomainNegotiationContext::setDomain() (or DomainNegotiator::getActiveDomain(TRUE) for the request-pushed case) instead of the deprecated DomainNegotiator::setActiveDomain() / setRequestDomain(). Bumps composer.json and every submodule info.yml that depends on a domain submodule to (>=3.1).
