Remove idea/src/META-INF/extensions/{kotlin2jvm.xml,kotlin2js.xml}

Keep the EnvironmentConfigFiles enum because its values are used in
determining whether the environment is going to be used for JVM or
non-JVM project analysis, but remove the actual files.

Drop EnvironmentConfigFiles.EMPTY and replace its only usage in
preprocessor with JVM_CONFIG_FILES: it's easier and won't affect
anything
