/**
 * Set's up all configurations and compilations needed for kotlin_jvm to work and defines proper task dependencies between them.
 *
 * ## Overview
 * General overview of what this function set's up to happen on each build the user performs on his code:
 * - Creates a `bootstrap.jar` which contains all glue code for the `cpp -> jvm -> cpp` communication but no user code.
 * This `bootstrap.jar` is loaded automatically at startup by the `cpp` side of the module
 * - Applies our kotlin symbol processor to the `main` configuration and compilation to automatically generate the entry files.
 * - Configures a `Shadow Jar (Fat Jar) which includes all dependencies.
 * - Uses the created `Shadow Jar` named `main.jar` together with the created `godot-bootstrap.jar` at startup
