[Feature] Support s390x bootloader installation using zipl
Metadata
Current evaluation
Add s390x bootloader support via zipl, skipping GRUB and generating /etc/zipl.conf; the feature is open, unlabeled, and awaiting maintainer triage.
Suggested action: needs triage
Reason: The request gives concrete steps—skip GRUB, generate /etc/zipl.conf, and invoke /sbin/zipl—and the current bootloader code has only EFI/BIOS methods with no s390x or zipl path. The issue has no labels, assignee, or comments, and target-disk mapping and zipl invocation details remain unspecified, so maintainer triage is still needed.

Issue body
### Feature Description
Add support for `s390x` (IBM Z / LinuxONE) bootloader installation using `zipl` (z/Architecture Initial Program Loader), bypassing GRUB.
### Implementation Details
1. **Bypass GRUB**:
- GRUB does not exist on `s390x`. Skip all GRUB module copying and `grub-mkimage` steps when target arch is `s390x`.
2. **`zipl` Configuration**:
- Generate `/etc/zipl.conf` detailing kernel, initrd, and boot parameters.
3. **`zipl` Execution**:
- Invoke `/sbin/zipl` to write IPL boot records to target DASD or SCSI disk sector offsets.
