There are operators in Blender that allow the user to import multiple files at the same time, however this functionality is only implemented when importing with blender's file browser, drag and drop files only takes first selected file. The patch adds support for drag and drop multiple files. Notes: * The files are filtered according to the extension of the first selected file. * Not all operators that import files support importing multiple files, so they will still import one. * Changes must be made to allow importers to read all file paths. This will be used in upcoming drag & drop import. Pull Request: https://projects.blender.org/blender/blender/pulls/107230
