Include custom editors in history (#83019)

Fixes #81824

The history service currently drops any editor input that are not `FileEditorInput`. This does not work for custom editors, which are always backed by a resource but do not subclass `FileEditorInput`

The fix here is to create history entries for any input that has a resource that is backed by the file-service
