Right now we're getting the info for the Cloud Hypervisor repo and
version, but we don't do anything with them, as those are not passed
down to the build script.
Morever, the build script itself gets the info from exactly the same
place when those are not passed, making those redundant.

Right now TDx support on Cloud Hypervisor is gated behind a "--features
tdx" flag. However, having TDx support enabled should not and does not
impact on the general usability of cloud-hypervisor.
As sooner than later we'll need kata-deploy binaries to be tested on a
CI that's TDx capable, for the confidential containers effort, let's
take the bullet and already enable it by default.
By the way, touching kata-deploy-binaries.sh as it's ensure the change
will be used in the following workflows:
* kata-deploy-push
* kata-deploy-test
* release

Various improvements to the top-level README file:
- Moved the following sections from the runtime's README to the
top-level README:
- License
- Platform support / Hardware requirements
- Added the following sections to the top-level README:
- Configuration
- Hypervisors
- Improved formatting of the Documentation section in the top-level
README.
- Removed some unused named links from the top-level README.
Also improvements to the runtime README:
- Removed confusing mention of the old 1.x runtime name.
- Clarify the binary name for the 2.x runtime and the utility program.

Let's allow passing down a build flag to cargo, when building Cloud
Hypervisor.
By doing this we allow calling this script with:

The current code will always pull the release binaries in case the
version requested by Kata Containers matches with a released version.
This, however, has a limitation of preventing users / CIs to build
cloud-hypervisor from source for a reason or another, such as passing a
specific build flag to cloud-hypervisor.
This is a pre-req to solving
https://github.com/kata-containers/kata-containers/issues/3671.
While here, a small changes were needed in order to improve readability
and debugability of why we're building something from the sources rather
than simply downloading and using a pre-built binary.

German Maglione, one of the current virtio-fs developers, has brought to
our attention that using "announce-submounts" could help us to prevent
inode number collisions.
This feature was introduced a year ago or so by Hanna Reitz as part of
the 08dce386e77eb9ab044cb118e5391dc9ae11c5a8, and as we already mandate
QEMU >= 6.1.0, let's take advantage of that.

In commit 78dff468bf1 we introduced logic to rewrite PCIDEVICE_ environment
variables for the container so that they contain correct addresses for the
Kata VM rather than for the host. Unfortunately, we never actually invoked
the function to do this.
It turns out we need to do this not only at container creation time, but
also for environment variables supplied to processes exec-ed into the
container after creation (e.g. with crictl exec). Add calls to make both
those updates.

add_devices() generates a mapping of host to guest PCI addresses which is
used to update some environment variables for the workload. Currently it
just does this locally, but it turns out we're going to need the same map
again in order to correct environment variables for processes exec-ed into
the existing container.
Move the map to the sandbox structure so we can keep it around for those
later uses.

This function updates PCIDEVICE_ environment variables (such as those
supplied by the Kubernetes SR-IOV plugin) in the OCI spec to be correct
for the Kata VM, rather than for the host.
We neglected to actually call this function, however, and it turns out that
when we do, we need to do things slightly different. We actually need to
adjust envionment variables both in the OCI spec when creating a container
and also in the variables supplied for exec-ing a new process within an
existing container.
Adjust the function so that it can be used for both these cases.
