Replace overcloud-secure with overcloud-partition

https://review.opendev.org/#/c/741319/ in tripleo-image-elements
moves partition handling from overcloud-secure to
overcloud-partition to create whole disk image.

It breaks the overclodu hardened images jobs with
DIB_BLOCK_DEVICE: unbound variable.

By updating the element to overcloud-partition
fixes the issue.

It also updates the elements for uefi.

Closes-Bug: #1888613
