feat(gradle): analyze a Gradle project's dependencies per configuration (#1181)

The Dependency Analyzer lists Gradle projects next to Maven modules. For a Gradle project it runs `<project>:dependencies --configuration <name>` (compile/runtime/test classpaths) in the background (on the project host for remote projects), cancellable and cached per session, and reuses the list/tree views, search, conflicts-only filter and usage paths: an exact request Gradle replaced (1.0 -> 1.1) is a conflict showing the requested version, constraints are left out, unresolved dependencies are marked and build projects (quoted or not) are recognised. Exclude / Jump to Source stay Maven-only. Opened from the Gradle tool window toolbar, a Gradle project's context menu and a build script's menus.

Closes #1005
