Remove reflection for removed class, remove deprecated graal-vm option

[Bhashit]

Motivation and Context

Removal of reflection-config for an unused class

The class in question has been removed from the source-code of this repo, but the reflection-config still refers to it. This causes GraalVM to generate an error. The resulting builds behave incorrectly.

Removal of a deprecated GraalVM option

The --allow-incomplete-classpath option is deprecated in GraalVM and generates warnings during builds.

The native-build fails to parse this file, it needs to at least have some content in it. Could you please leave an empty array here? You can can test locally what the native build test by looking at the buildspec/native-image-integ-test.yml file and reproducing locally, ie:

mvn clean install -pl :sdk-native-image-test -P quick --am -T1C
mvn clean install -pl :bom-internal,:bom
cd test/sdk-native-image-test
mvn clean package -P native-image
target/sdk-native-image-test
