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

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.
