Move package config to an interface

* Change `PackageConfig` to an interface
* Move JAR-specific configuration to `JarConfig` group
* Replace package type with combination of JAR type and JAR/native enable flags
* Introduce compatibility interceptors for complex remappings
* Update all build steps, tests, and POMs to use the new properties
