We stop supporting tinyipa entirely and switch all jobs to use
DIB-based (diskimage-builder) IPA images.
Renamed all CI jobs as we use DIB-based IPA ramdisks only now.
Increased test VM memory from 1024 MB to 4096 MB to accommodate
larger DIB-based IPA ramdisks (~500 MB vs ~80 MB for tinyipa).
Kept 3 jobs with their legacy name despite they use DIB-based
IPA ramdisks now as other projects still use them.
