This commit removes jQuery file uploader from Discourse,
completing the transition to Uppy. The image-uploader
and UploadMixin components are also removed in this commit
as they have already been replaced and are the only things
using jQuery file upload.

The smoke test has been failing with the error:
```
TypeError: Cannot read properties of undefined (reading 'Core')
```
Since de20c46077
and 9873a942e3 this error has been occurring,
possibly now because Uppy is required by a plugin. Adding uppy.js into
the require list for theme_qunit_vendor.js fixes the issue.
The `ember_jquery` bundle contains production builds of Ember and jQuery
which doesn't work with tests. This commits introduces a new
`theme_qunit_vendor` bundle which is copy of the `vendor` bundle but
doesn't contain `ember_jquery`.
