Make the OpenTelemetry Logback appender work with GraalVM native imag…

…es (#7989) I have tried the [OpenTelemetry Logback appender](https://github.com/open-telemetry/opentelemetry-java-instrumentation/tree/main/instrumentation/logback/logback-appender-1.0/library) with GraalVM native images. The GraalVM configurations of this PR are required to make it work. It's my first GraalVM-related PR in this repo. In future works, adding automatic tests with GraalVM on some [programmatic instrumentation libraries](https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/docs/supported-libraries.md#libraries--frameworks) may be interesting.
