docs: Update OVMF related documentation

Since we moved to the CloudHvX64 target from EDK2, we can't use the same
OVMF firmware for both Cloud Hypervisor and QEMU. The documentation
needed some updates.

To make Cloud Hypervisor use UEFI boot, pass the `CLOUDHV.fd` file path as an argument to the `--kernel` option. The firmware file will be opened in read only mode.
The same firmware can be used with Cloud Hypervisor or with QEMU. This is particularly useful if using QEMU for the preparation phase.

- QEMU, version >=5.0.0 is recommended.
- Windows installation ISO. Obtained through MSDN, Visual Studio subscription, evaluation center, etc.
- [VirtIO driver ISO](https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/)
- Suitable [OVMF](uefi.md) firmware
- Suitable firmware for Cloud Hypervisor (`CLOUDHV.fd`) and for QEMU (`OVMF.fd`)
- With the suggested image size of 30G, there should be enough free disk space to hold the installation ISO and any other necessary files
This step currently requires QEMU to install Windows onto the guest. QEMU is only used at the preparation stage, the resulting image is then fully functional with Cloud Hypervisor.
