DM: update launch scripts to use OVMF.fd directly from the rootfs

* Update the launch scripts provided as examples on how to launch a Zephyr,
VxWorks or Windows User VM to directly use the 'OVMF.fd' bios file installed
by default in '/usr/share/acrn/bios/'
* Remove the OVMF.fd that was kept under 'doc/tutorials' (no longer needed)
* Adapt the tutorials to reflect this change
