Use suppressed exceptions to provide detailed library loading errors

[sidepelican]

Previously, when System.loadLibrary failed, the specific underlying errors were not being exposed.

For instance, libSwiftJava depends on libFoundationEssentials, which in turn depends on libswiftSynchronization.so. If libswiftSynchronization is missing from the runtime environment, the error message would simply report a generic SwiftJava loading failure. This is confusing.

Caused by: java.lang.RuntimeException: Failed to load SwiftJava from java.library.path and JAR resources

This PR updates the loading logic to collect and expose all encountered errors by utilizing Throwable.addSuppressed().

Caused by: java.lang.RuntimeException: Failed to load 'SwiftJava'. See suppressed exceptions for details.
