Implements "PerspectiveConfiguration" inside kie-wb-common-kogito-webapp-base so that it is possible to re-use the AuthoringPerspective regardless of "runtime" or "testing" showcases.
For the moment being, only configurable value is

Class<? extends AbstractWorkbenchPanelPresenter> perspectivePanelType

, default for which will be

StaticWorkbenchPanelPresenter.class

(to be used in "runtime" environment, like VS code).
"Testing" showcases should provide a

javax.enterprise.inject.Alternative

"PerspectiveConfiguration"

Refactor DMNVFSService inside kie-wb-common-kogito-webapp-base to have it available by all kogito editors
