* Support multiple plugin source paths
* Refactor: remove unncessary PathLookup method.
It's only called in one place, and there's no need to override it for testing.
Removing it just makes things simpler.
* Refactor: local var for pathLookup
* Fix bugs in test build info parsing
* Fix representative_class in test
* Move BridgeUtilTests.
Tests in org.elasticsearch.entitlement.bridge are going to be uniquely hard to
test once we patch the bridge into java.base, due to Java's prohibition on
split packages.
Let's just move this guy to another package.
* Upcast (?!) Java23EntitlementChecker to EntitlementChecker
* Empty TestPathLookup
* Create PolicyManager during bootstrap, allowing us to share initialization
* Use empty component path list instead of null
* Downcast to the class of the check method.
In our unit test, we have a mock checker that doesn't extend
EntitlementChecker, so downcasting to that would require us to needlessly
rework the unit test.
* Fix javadoc typos
