refactor: kotlin multi-platform [DHIS2-16221]

[jbee]

• replaces @AutoValue with records (and interfaces for hierarchies)
• replaces joda-time with java.time
• replaces @Nullable with @CheckForNull and removes javax dependency
• replaces used StringUtils.isEmpty with plain java and removes common lang dependency
• replace assertj with vanilla junit
• replace equalsverifier with vanilla junit (records do not need equals checked)
• remove mockito dependency (was not needed any more)
• replace slf4j with java.util.logging (was just some debug and error logging in one class)
• removed apache commons util dependency (replaced with vanilla java)
• replace Arrays.asList with List.of
• move tests of expression parser internals to the expression parser repo (test: moved from rule engine repo expression-parser#35)
• use kotlin MP JVM artefact of the expression parser

Any failing test that would only check that a factory method did throw a NPE for non-null arguments were removed as in kotlin we will have non-null types for these so no check or test is needed. The existing tests mainly confirmed a behaviour of @AutoValue that would generate null checks in the constructor for fields annotated with @Nonnull.

Created the KMP structure. The version has been set to 3.0.0-SNAPSHOT.

The github action is configured to push a SNAPSHOT version on each PR. Publication to Maven Central has been disabled to avoid accidental publications during the refactor.

All the classes have added to jvmMain because of dependencies with Java classes. There are two classes added to commonMain just to make the common artifact non-empty (native build crashes if it is empty, it looks like a bug).

Pending Java classes to remove:

• java.util.logging.Level
• java.util.logging.Logger
• java.text.SimpleDateFormat
• java.util.Date
• java.util.Locale
• java.util.concurrent.Callable
• java.util.Map
• java.util.regex.Pattern
