Remove the initramfs folder, its build steps, and use the kernel
based dm-verity enforcement for the handlers which used the
initramfs mode. Also, remove the initramfs verity mode
capability from the shims and their configs.

This change introduces the kernelinit dm-verity mode, allowing
initramfs-less dm-verity enforcement against the rootfs image.
For this, the change introduces a new variable with dm-verity
information. This variable will be picked up by shim
configurations in subsequent commits.
This will allow the shims to build the kernel command line
with dm-verity information based on the existing
kernel_parameters configuration knob and a new
kernel_verity_params configuration knob. The latter
specifically provides the relevant dm-verity information.
This new configuration knob avoids merging the verity
parameters into the kernel_params field. Avoiding this, no
cumbersome escape logic is required as we do not need to pass the
dm-mod.create="..." parameter directly in the kernel_parameters,
but only relevant dm-verity parameters in semi-structured manner
(see above). The only place where the final command line is
assembled is in the shims. Further, this is a line easy to comment
out for developers to disable dm-verity enforcement (or for CI
tasks).
This change produces the new kernelinit dm-verity parameters for
the NVIDIA runtime handlers, and modifies the format of how
these parameters are prepared for all handlers. With this, the
parameters are currently no longer provided to the
kernel_params configuration knob for any runtime handler.
This change alone should thus not be used as dm-verity
information will no longer be picked up by the shims.
systemd-analyze on the coco-dev handler shows that using the
kernelinit mode on a local machine, less time is spent in the
kernel phase, slightly speeding up pod start-up. On that machine,
the average of 172.5ms was reduced to 141ms (4 measurements, each
with a basic pod manifest), i.e., the kernel phase duration is
improved by about 18 percent.

For docker-based builds only install Rust when necessary.
Further, execute the detect Rust version check only when
intending to install Rust.
As of today, this is the case when we intend to build the
agent during rootfs build.

We set the VERSION variable consistently across Makefiles to
'unknown' if the file is empty or not present.
We also use git commands consistently for calculating the COMMIT,
COMMIT_NO variables, not erroring out when building outside of
a git repository.
In create_summary_file we also account for a missing/empty VERSION
file.
This makes e.g. the UVM build process in an environment where we
build outside of git with a minimal/reduced set of files smoother.

Create a guest image to support SELinux for containers inside the guest
if `SELINUX=yes` is specified. This works only if the guest rootfs is
CentOS and the init service is systemd, not the agent init. To enable
labeling the guest image on the host, selinuxfs must be mounted on the
host. The kata-agent will be labeled as `container_runtime_exec_t` type.

It would be nice to use `versions.yaml` for the maintainability.
Previously, we have been specified the `libseccomp` and the `gperf` version
directly in this script without using the `versions.yaml` because the current
snap workflow is incomplete and fails.
This is because snap CI environment does not have kata-cotnainers repository
under ${GOPATH}. To avoid the failure, the `rootfs.sh` extracts the libseccomp
version and url in advance and pass them to the `install_libseccomp.sh` as
environment variables.

Remove a lot of cruft of musl installations -- we needed those for the
Go agent, but Rustup just takes care of everything. aarch64 on
Debian-based & Alpine is an exception -- create a symlink
`aarch64-linux-musl-gcc` to `musl-tools`'s `musl-gcc` or `gcc` on
Alpine. This is unified -- arch-specific Dockerfiles are removed.

The osbuilder scripts include a bunch of code for installing cmake, even
though cmake is never invoked. versions.yaml claims it's needed to build
grpc-rs, but that doesn't appear to be in our dependency graph.
Presumably, we used to need this, but don't any more. So, remove all cmake

Since we always build musl kata-agent, there is no need to build
it inside a musl container. We can just build on the host and then
copy the binary to the target rootfs.
There are still a lot to clean up and it should be made so for ALL
target distros instead of just alpine. But this is at least working
for alpine first.
