Adds initial support for File Handler registration with the python API for design task #68935. File Handlers will allow developers to associate additional UI behavior and capability to operators traditionally used only within the file browser. The initial commit should have no user visible changes, but will serve as the foundation for providing file drag & drop capabilities to operators that can manage files (#111242). See the PR for an example of python usage. See design task #68935 for remaining work to be explored in the future. Pull Request: https://projects.blender.org/blender/blender/pulls/112466
