Add qemu support for secureboot testing via `talosctl cluster create`.
Can be tested via:
```bash
sudo -E _out/talosctl-linux-amd64 cluster create --provisioner=qemu $REGISTRY_MIRROR_FLAGS --controlplanes=1 --workers=1 --iso-path=_out/talos-uki-amd64.iso --with-secureboot=true --with-tpm2=true --skip-injecting-config --with-apply-config
```
This currently only supports just booting Talos in SecureBoot mode.
Installation and Upgrade comes as extra PRs.
Fixes: #7324
