Upgraded to java 17, switched to gradle, added new G-Mem for mac

- uses badass runtime plugin to create platform-specific images (https://badass-runtime-plugin.beryx.org/releases/latest/).
- uses kotlin based gradle build script.
- uses openjfx's plugin to obtain the required javafx modules
- added G-Wasm jar to repo for now, maven link is broken for me
- added g_mem_mac executable (https://github.com/dorving/g_mem_mac)
- added MacOS readable icon (.icns format)
- removed unused and broken imports from PortRequester.java and GEarth.java
- added GEarthLauncher.java (see docs for reason)
