00aadfe20a introduced a regression on
`make cc-tdx-kernel-tarball` as we stopped passing all the needed
information to the `build-kernel.sh` script, leading to requiring `yq`
installed in the container used to build the kernel.
This commit partially reverts the faulty one, rewritting it in a way the
old behaviour is brought back, without changing the behaviour that was
added by the faulty commit.

This removes two options that are not needed (any longer). These
are not set for any kernel so they do not need to be ignored either.

The agent configuration file, which is part of the docs, is used by the
confidential containers CIs and, right now, cannot be run behind a
firewall, which is exactly how the TDX CIs are reunning, as https_proxy
is not set there.

As the previous commit added a new runtime class to be used with TDX,
let's make sure this gets shipped and configured as part of the
kata-deploy-cc script, which is used by the Confidential Containers
Operator.
This commit also cleans up all the extra artefacts that will be
installed in order to run the CLH TDX workloads.

Let's add a new configuration file for using a cloud hypervisor (and all
the needed artefacts) that are TDX capable.
This PR extends the Makefile in order to provide variables to be set
during the build time that are needed for the proper configuration of
the VMM, such as:
* Specific kernel parameters to be used with TDX
* Specific kernel features to be used when using TDX
* Artefacts path for the artefacts built to be used with TDX
* Kernel
* TD-Shim
The reason we don't hack into the current Cloud Hypervisor configuration
file is because we want to ship both configurations, with for the
non-TEE use case and one for the TDX use case.
It's important to note that the Cloud Hypervisor used upstream is
already built with TDX support.

TDX kernel is based on a kernel version which doesn't have the
CONFIG_SPECULATION_MITIGATIONS option.
Having this in the allow list for missing configs avoids a breakage in
the TDX CI.

The runtime will crash when trying to resize memory when memory hotplug
is not allowed.
This happens because we cannot simply set the hotplug amount to zero,
leading is to not set memory hotplug at all, and later then trying to
access the value of a nil pointer.

While doing tests using `ctr`, I've noticed that I've been hitting those

Till we find the root cause of the issue (which is *not* in the Kata
Containers), let's increase the timeouts when dealing with a
Confidential Guest.

When booting the TDX kernel with `tdx_disable_filter`, as it's been done
for QEMU, VirtioFS can work without any issues.
Whether this will be part of the upstream kernel or not is a different
story, but it easily could make it there as Cloud Hypervisor relies on
the VIRTIO_F_IOMMU_PLATFORM feature, which forces the guest to use the
DMA API, making these devices compatible with TDX.
See Sebastien Boeuf's explanation of this in the
3c973fa7ce208e7113f69424b7574b83f584885d commit:
"""
By using DMA API, the guest triggers the TDX codepath to share some of
the guest memory, in particular the virtqueues and associated buffers so
that the VMM and vhost-user backends/processes can access this memory.

configuration in kata configuration file or in pod anotation file.
And information of those modules will be sent to kata agent when
