[MNG-8015] Adjustments in new API related to PathType (#1501) 

* Javadoc cleanup and replacement of some `System.getProperty("...")` by more specific standard methods.

* Add Type.PROCESSOR, MODULAR_PROCESSOR and CLASSPATH_PROCESSOR.

* Modification of the path type API:

* Add a `warningForFilenameBasedAutomodules()` method in `DependencyResolverResult`.
* Add relationships from `JavaPathType` to `javax.tool` location API.
* Modify the `PathType.option(Iterable<? extends Path>)` return type
  because the option and the value need to be two separated arguments.

* Fixes according some comments on the pull request.
