We need a way to opt-out of this behavior in case it causes issues (for example due to forgetting to update the constant pool parser). Probably via an env variable or ML arg.

This PR introduces a new
constantsFiltermethod onILaunchPluginService. The intent of this is to allow transformers like RuntimeDistCleaner to be implemented more efficiently, by skipping parsing of the class file if the constant pool does not contain a given byte sequence. This should work because if theDistannotation were to be present in the class, it would have to be in the constant pool.Using this feature is optional and existing
ILaunchPluginServiceimplementations will continue to work as before without changes.
