ZTS: Use QEMU for tests on Linux and FreeBSD

This commit adds functional tests for these systems: - AlmaLinux 8, AlmaLinux 9 - ArchLinux - CentOS Stream 9 - Fedora 39, Fedora 40 - Debian 11, Debian 12 - FreeBSD 13, FreeBSD 14, FreeBSD 15 - Ubuntu 22.04, Ubuntu 24.04 Workflow for each operating system: - install QEMU on the github runner - download current cloud image - start and init that image via cloud-init - install deps and poweroff system - start system and build openzfs and then poweroff again - clone the system and start 3 qemu machines for tests - use trimable virtual disks (3x 2GB) - do the functional testings in < 3h Signed-off-by: Tino Reichardt <milky-zfs@mcmilk.de> Co-authored-by: Tony Hutter <hutter2@llnl.gov>

+Workflow for each operating system:
+ - install QEMU on the github runner
+ - download current cloud image
+ - start and init that image via cloud-init
+ - install deps and poweroff system
+ - start system and build openzfs and then poweroff again
+ - clone the system and start 4 qemu workers for the testings (4x 3GB RAM)
+ - use trimable virtual disks (3x 1GB) for each testing system
+ - do the functional testings < 3h for each os
