Update the directory structure for the Android plugin addon

The addon directory now contains two subfolders:
- "addons/<plugin_dir>/export":
  - should contain the editor plugin script and the editor export plugin script. as well as any binaries needed for export
  - `plugin.cfg` must point to the editor plugin script in this directory
  - must contain a `.gdignore` file to exclude this directory from the export process
- "addons/<plugin_dir>/interface":
  - optional directory
  - can contain helper gdscript files used by the project to interface with the functionality exposed by the plugin
