This change introduces a new command line option `--vm`
to boot up a pod VM for testing. The tool connects with
kata agent running inside the VM to send the test commands.
The tool uses `hypervisor` crates from runtime-rs for VM
lifecycle management. Current implementation supports
Qemu & Cloud Hypervisor as VMMs.
In summary:
- tool parses the VMM specific runtime-rs kata config file in
/opt/kata/share/defaults/kata-containers/runtime-rs/*
- prepares and starts a VM using runtime-rs::hypervisor vm APIs
- retrieves agent's server address to setup connection
- tests the requested commands & shutdown the VM

Route kata-shim logs directly to systemd-journald under 'kata' identifier.
This refactoring enables `kata-shim` logs to be properly attributed to
'kata' in systemd-journald, instead of inheriting the 'containerd'
identifier.
Previously, `kata-shim` logs were challenging to filter and debug as
they
appeared under the `containerd.service` unit.
This commit resolves this by:
1. Introducing a `LogDestination` enum to explicitly define logging
targets (File or Journal).
2. Modifying logger creation to set `SYSLOG_IDENTIFIER=kata` when
logging
to Journald.
3. Ensuring type safety and correct ownership handling for different
logging backends.
This significantly enhances the observability and debuggability of Kata
Containers, making it easier to monitor and troubleshoot Kata-specific
events.

This series should make runtime-rs's vcpu allocation behaviour match the
behaviour of runtime-go so we can now enable pertinent tests which were
skipped so far due the difference between both shims.

Configuration information is adjusted after loading from file but so
far, there has been no similar check for configuration coming from
annotations. This commit introduces re-adjusting config after
annotations have been processed.
A small refactor was necessary as a prerequisite which introduces
function TomlConfig::adjust_config() to make it easier to invoke
the adjustment for a whole TomlConfig instance. This function is
analogous to the existing validate() function.
The immediate motivation for this change is to make sure that 0
in "default_vcpus" annotation will be properly adjusted to 1 as
is the case if 0 is loaded from a config file. This is required
to match the golang runtime behaviour.

This commit addresses a part of the same problem as PR #7623 did for the
golang runtime. So far we've been rounding up individual containers'
vCPU requests and then summing them up which can lead to allocation of
excess vCPUs as described in the mentioned PR's cover letter. We address
this by reversing the order of operations, we sum the (possibly fractional)
container requests and only then round up the total.
We also align runtime-rs's behaviour with runtime-go in that we now
include the default vcpu request from the config file ('default_vcpu')
in the total.
We diverge from PR #7623 in that `default_vcpu` is still treated as an
integer (this will be a topic of a separate commit), and that this
implementation avoids relying on 32-bit floating point arithmetic as there
are some potential problems with using f32. For instance, some numbers
commonly used in decimal, notably all of single-decimal-digit numbers
0.1, 0.2 .. 0.9 except 0.5, are periodic in binary and thus fundamentally
not representable exactly. Arithmetics performed on such numbers can lead
to surprising results, e.g. adding 0.1 ten times gives 1.0000001, not 1,
and taking a ceil() results in 2, clearly a wrong answer in vcpu
allocation.
So instead, we take advantage of the fact that container requests happen
to be expressed as a quota/period fraction so we can sum up quotas,
fundamentally integral numbers (possibly fractional only due to the need
to rewrite them with a common denominator) with much less danger of
precision loss.

When hot-plugging CPUs on QEMU, we send a QMP command with JSON
arguments. QEMU 9.2 recently became more strict[1] enforcing the
JSON schema for QMP parameters. As a result, running Kata Containers
with QEMU 9.2 results in a message complaining that the core-id
parameter is expected to be an integer:
```
qmp hotplug cpu, cpuID=cpu-0 socketID=1, error:
QMP command failed:
Invalid parameter type for 'core-id', expected: integer
```
Fix that by changing the core-id, socket-id and thread-id to be
integer values.

This auto-detects the repo by default (instead of having to specify
KATA_DEV_MODE=true) so that forked repos can leverage the static-checks.yaml CI
check without modification.
An alternative would have been to pass the repo in static-checks.yaml. However,
because of the matrix, this would've changed the check name, which is a pain to
handle in either the gatekeeper/GH UI.

In order to have a reproducible code generation process, we need to pin
the versions of the tools used. This is accomplished easiest by
generating inside a container.
This commit adds a container image definition with fixed dependencies
for Golang proto/ttrpc code generation, and changes the agent Makefile
to invoke the update-generated-proto.sh script from within that
container.

The generated Go bindings for the agent are out of date. This commit
was produced by running
src/agent/src/libs/protocols/hack/update-generated-proto.sh with
protobuf compiler versions matching those of the last run, according to
the generated code comments.
Since there are new RPC methods, those needed to be added to the
HybridVSockTTRPCMockImp.
