The KATA_BUILD_CC variable plus the existence (or not) of the initramfs
were used to determine whether to build the kernel for measured rootfs
or not. Currently the variable MEASURED_ROOTFS has been used
to trigger the feature build and when it is activated it should expect
the initramfs exist. In other words, this changed the kernel build
so that if `MEASURED_ROOTFS=yes` then the initramf file must exist and
be found.

By convention the caller of tools/packaging/kernel/build-kernel.sh changes
the script behavior by passing arguments, whereas, for measured rootfs
it has used an environment variable (MEASURED_ROOTFS). This refactor
the script so that the caller now must pass the "-m" argument to enable
the build of the kernel with measured rootfs support.

The virtio vsock driver has a small window during initialization
where it can silently drop replies to connection requests.
Because no reply is sent, kata waits for 10 seconds and in the
end it generates a connection timeout error in HybridVSockDialer.

There were recent changes for the tdx kernel in the version.yaml that are
not currently accounted for in the build-kernel.sh script.
Attempts to setup a tdx kernel to build local changes seemed to not download
the tdx kernel. Instead the mainline kernel is downloaded which has no
tdx-related changes.
The version.yaml has a new entry for tdx kernel. Use that instead for
setting up and downloading the tdx kernel.

Upcall is a direct communication tool between VMM and guest developed
upon vsock. The server side of the upcall is a driver in guest kernel
(kernel patches are needed for this feature) and it'll start to serve
the requests after the kernel starts. And the client side is in
Dragonball VMM , it'll be a thread that communicates with vsock through
uds.
We want to keep the lightweight of the VM through the implementation of
the upcall, through which we could achieve vCPU hotplug, virtio-mmio
hotplug without implementing complex and heavy virtualization features
such as ACPI virtualization.

CONFIG_X86_SGX is introduced after kernel 5.11, and that config is a
default x86_64 config for Kata build-kernel.sh script.
But if we use -v to specify any kernel version below 5.11 will cause an
inevitable error because CONFIG_X86_SGX is not supported in older
kernels and that may cause problem for the situation if we need kernel
version below 5.11.
So I propose to put CONFIG_X86_SGX into whitelist.conf to avoid break
building guest kernel below 5.11.

The previously used repo has been removed by Intel. As this happened,
the TDX team worked on providing the patches that were hosted atop of
the v5.15 kernel as a tarball present in the
https://github.com/intel/tdx-tools repos, see
https://github.com/intel/tdx-tools/pull/161.
On the Kata Containers side, in order to simplify the process and to
avoid adding ~1400 kernel patches to our repo, we've revived the
https://github.com/kata-containers/linux repo, and created a branch and
a tag with those ~1400 patches atop of the v5.15. The branch is called
v5.15-plus-TDX, and the tag is called 5.15-plus-TDX (in order to avoid
having to change how the kernel builder script deals with versioning).
Knowing the whole background, let's switch the repo we're getting the
TDX kernel from.
