DEV: Use Uppy in wizard-field-image uploads (#15269)
We cannot use any of the uppy mixins or core code, because
the code there is not shared with the wizard, and to move
it all to discourse-common would be a task almost equal
difficulty to taking the ring to Mordor.

Therefore, we can just use the uppy vendor libraries in the
wizard, and do a quick-n-dirty version of the uppy upload
code for the wizard-field-image uploader.
