[SE-4631] feat: add CCX ID to generated filename prefixes (#27028)

This is the backport of https://github.com/edx/edx-platform/pull/27028.

---

This pull requests backport a feature to include CCX course IDs in the generated course filenames used for downloading reports, etc.

The suffix appended to the generated filename prefix is following the <separator>_ccx_<ccx id> pattern, to ensure unique filename generation per ccx - previously all CCX courses were downloaded with the same name.
