CIDR: New way of building CLion and AppCode plugins

- Move `prepare/cidr-plugin`, `prepare/clion-plugin` and `prepare/appcode-plugin` modules from `kotlin` to `kotlin-ultimate` project
- Move `versions.clion.*` and `versions.appcode.*` properties from `kotlin` to `kotlin-ultimate` project
- Drop `cidr183` bunch in `kotlin` project
- Drop useless `cidrPluginDir`, `clionPluginDir`, `clionSandboxDir`, `appcodePluginDir`, `appcodeSandboxDir` Gradle properties in `kotlin` project
- Drop `cidrPlugin` Gradle task in `kotlin` project
- Total: Add ability to build `kotlin-ultimate` both as part of multi-project build with `kotlin` project, and as a standalone build
