feat(gradle): link and unlink independent Gradle builds (#1413)

Opening a folder of independent Gradle builds selected only the first build. Link Gradle Projects… (pick a build's settings or build file) and Unlink on a build's root let an ordinary project window manage several independent builds without changing their scripts. The build model holds a list of Gradle builds; each keeps its own wrapper, working directory, environment, task routing and sync cache, keyed by the owning build directory. The links persist in the project's Gradle settings (linkedProjects); unlinking leaves files and saved run configurations alone. Existing includeBuild support is unchanged, and an explicitly linked build takes precedence over a composite that also includes it. Workspace windows keep Link/Unlink disabled.
