Enhance the Xen python tests to exercise block devices: this boils down
to switching from ramdisks to disk partitions for the domains rootfs.
(Refer to the comments in the python script for block devices details.)
- Add support for PCI and Xen block to the Linux kernel configurations.
- Add a few commands to list the xvda block device for good measure.
- Generate two partitions with the rootfs in the disk images; we use the
same rootfs contents twice, once for each domain.
- Add a paravirtualized block device to the Xen dom1 configurations and
adjust both domains kernel command lines, to specify the rootfs
locations.
- Build host-qemu for Arm v7, to workaround an issue with 32b Arm and
old Qemu versions, which is what we have on CI currently.
- While at it, bump Linux kernel to 6.18.4 and U-Boot to 2026.01.
