When the Issuable Default Template feature is not available, do not
show the input form to configure the Issue & MR templates on the
Settings page.

Only when the Issuable Default Templates feature is available, fill in
the description from settings when building a new MR.

Only when the license allows Issuable Default Templates, set the issue
description when building an Issue.

Do this by splitting out EE-specific features into
EE::Issues::BuildService. And also split up spec files.
