Add full native image support and CI coverage

MariaDB Connector/J cannot connect to a database when running as a GraalVM native image.

The driver's internal configuration system uses reflection to map JDBC URL properties to Configuration$Builder setter methods at runtime.
GraalVM's AOT compiler removes those methods during the native image build since they are not declared in any reflect-config.json, causing a hard NoSuchMethodException on the first connection attempt.

This task covers both fixing the root cause and adding a CI job to prevent future regressions.

graal has dedicated configuration file : https://github.com/oracle/graalvm-reachability-metadata/blob/master/metadata/org.mariadb.jdbc/mariadb-java-client/3.5.2/reachability-metadata.json
but there is some missing part there.
