Refresh our README in a consistent style and update it to reflect:
* A recommendation to use binaries
* Clarify our relationship with other Rust based VMMs/Rust-VMM project
* Ensure instructions result in a usable image (cloud-init)
* Simplify script instructions
* Move compilation details elsewhere
* Add Fedora 36 image details
* Point to CLOUDHV as well as Rust Hypervisor Firmware

Packages targeting various distributions are now available thanks to the
Open Bulid Service. The SPECS have been moved to a separate repo under
https://github.com/cloud-hypervisor/obs-packaging
which documents how to include pre-compiled binaires in a supported
distribution. Besides the Cloud Hypervisor itself, accompanying pieces
like UEFI bins are available, too.
Any contributions to the packaging can be also accepted in
the aforementioned repo. Further integration with the OBS like PR
validation is to be targeted there, too, as far as it can get. As the
packaging topic has moved in a separate repo, the bundled SPEC became
obsolete is suggested for removal.

Since virtio-iommu is now part of the upstream Linux kernel, the main
reason for having our own Linux kernel fork is to carry the patches for
virtio-watchdog support.

virtio-net: fix for skb_over_panic inside big mode
commit 126285651b7f ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net")
accidentally reverted the effect of
commit 1a8024239da ("virtio-net: fix for skb_over_panic inside big mode")
on drivers/net/virtio_net.c
As a result, users of crosvm (which is using large packet mode)
are experiencing crashes with 5.14-rc1 and above that do not
occur with 5.13.

Current `Getting Started` section only contains steps for the x86_64
platform, as we have a documentation doing the same thing for AArch64,
we can point users to the correct documentation.
Also, this commit modifies the `docs/arm64.md` to fit the documentation
style within the project.

Moving to the latest kernel 5.14 simplifies greatly the list of patches
that we need to carry. Since virtio-iommu has been merged as part of the
5.14 release, the only remaining patches are virtio-watchdog and the EFI
reboot.

Since using the VIRTIO configuration to expose the virtual IOMMU
topology has been deprecated, the virtio-iommu implementation must be
updated.
In order to follow the latest patchset that is about to be merged in the
upstream Linux kernel, it must rely on ACPI, and in particular the newly
introduced VIOT table to expose the information about the list of PCI
devices attached to the virtual IOMMU.
