Kotlin Window Management library

Goals

• Provide a simple enough Kotlin API for interacting with OS
• Support all major desktop platforms: Linux, MacOS and Windows for now
• Make it Kotlin Multiplatform in future

Non-Goals

• Providing bindings for Android or iOS. It's too different from Desktop
• Bindings for browser API
• API alignment across platforms. Desktop platforms are different and provide different capabilities, we are not going to hide this difference. Though for some common APIs we could provide a layer that simplifies usage of it across the platforms
