Returns all builds contained in this build that should be imported into an IDE.

This is not always the same the builds returned by getIncludedBuilds. For the root build, the set of importable builds contains all builds that participate in the composite build, including those directly included by the root build plus all builds included transitively. For Gradle 7.2 and later, this set also includes any `buildSrc` builds that may be present. For all other builds, this set is empty.

Note that this set does not include the root build itself.
