Feature non-zipped actions artifacts (action v7) (#36786)

- content_encoding contains a slash => v4 artifact
- updated proto files to support mime_type and no longer return errors for upload-artifact v7
- json and txt files are now previewed in browser
- normalized content-disposition header creation
- azure blob storage uploads directly in servedirect mode (no proxying data)
- normalize content-disposition headers based on go mime package
  - getting both filename and filename* encoding is done via custom code

Closes #36829
