Report dd-java-agent itself as a Maven dependency in SCA telemetry

Generate META-INF/maven/com.datadoghq/dd-java-agent/pom.properties at
build time so the SCA dependency pipeline (JarReader → DependencyResolver)
detects com.datadoghq:dd-java-agent in the APP_DEPENDENCIES_LOADED
telemetry events.

Add a unit test in DependencyResolverSpecification verifying the resolver
correctly parses the generated pom.properties, and extend the
AbstractServerSmokeTest tracer-dependency assertion to include
com.datadoghq:dd-java-agent so all server smoke tests validate this
end-to-end against the real shadow JAR.
