Allow using PluginLoader classpath API from Bukkit plugins (#10758)

Browse Source 
Allows using the PluginLoader API without any of the other changes imposed by switching to a paper-plugin.yml.

Used by setting paper-plugin-loader in plugin.yml to the class name of your PluginLoader.

Also allows skipping the libraries field by setting paper-skip-libraries to true (by default both libraries and jars provided by the PluginLoader are added to the classpath).
