Create a copy of the 3.0 IDF on both 'amd64' and 'i386' paths
Type of work:
The idea is to have the same IDF for 3.0 copied on both:
This would be a way to have both:
- The current DAVE download 3.0 from the i386 IDF that it is coded to check.
- The future DAVE download 3.0 from the amd64 IDF once we did #12494.
