[GSoC2024] Decode uploaded filename from request header

[AndrewLuGit]

Motivation and context

This fixes issue #6528, as filenames with special characters must be decoded from the MIME header back into UTF-8.

How has this been tested?

Thanks for the contribution!

Please consider to add a API test to check this case.

Please make sure that other upload-related functions work with such characters in file names.

Bulk (non-TUS) uploads work fine. I'm not sure how to do remote and cloud uploads. Can I test those through the testing framework?

@azhavoro I'm not sure how to add the API test case, since this problem only happens through TUS uploads. How do I make sure a file is uploaded through TUS using the testing framework? Does the test case need to be in cypress instead of pytest?

Yes, it looks like the cypres test is the easiest way to initiate uploading via TUS.
