Remove GWT modules

All GWT related modules have been removed from nuxeo-jsf-ui repository: nuxeo-annot-api nuxeo-annot-contrib nuxeo-annot-core nuxeo-annot-http nuxeo-annot-repo nuxeo-platform-imaging-tiling nuxeo-platform-imaging-tiling-preview The PictureTilesRestlets restlet related to the nuxeo-platform-imaging-tiling has also been removed: the endpoint /nuxeo/restAPI/getTiles/ does not exist anymore. All GWT artifacts in the Nuxeo root pom dependencyManagement have also been removed. If you depend on those ones, you must update your project pom to add them. The related nuxeo.old.jsf.preview (introduced with NXP-25110 ) and nuxeo.text.annotations configuration properties that were used to activate the old preview and the GWT text annotations have been removed: setting them has no impact.
