Kata runtime employs a CapabilityBits mechanism for VMM capability
governance. Fundamentally, this mechanism utilizes predefined feature
flags to manage the VMM's operational boundaries.
To meet demands for storage performance and security, it's necessary
to explicitly enable capability flags such as `BlockDeviceSupport`
(basic block device support) and `BlockDeviceHotplugSupport` (block
device hotplug) which ensures the VMM provides the expected caps.
In CoCo scenarios, due to the potential risks of sensitive data leaks
or side-channel attacks introduced by virtio-fs through shared file
systems, the `FsSharingSupport` flag must be forcibly disabled. This
disables the virtio-fs feature at the capability set level, blocking
insecure data channels.

Two key important scenarios:
(1) Support `virtio-blk-pci` cold plug capability for confidential guests
instead of nvdimm device in CVM due to security constraints in CoCo cases.
(2) Push initdata payload into compressed raw block device and insert it
in CVM through `virtio-blk-pci` cold plug mechanism.

On newer TDX platforms, checking `/sys/firmware/tdx` for `major_version` and
`minor_version` is no longer necessary. Instead, we only need to verify that
`/sys/module/kvm_intel/parameters/tdx` is set to `'Y'`.
This commit addresses the following:
(1) Removes the outdated check and corrects related code, primarily impacting
`cloud-hypervisor`.
(2) Refines the TDX platform detection logic within `arch_guest_protection`.

Currently, the TDX Quote Generation Service (QGS) connection in QEMU is
hardcoded to vsock port 4050, which limits flexibility for TD attestation.
While the users will be able to modify the QGS port. To address this
inflexibility, this commit introduces a new qgs_port field within security
info and make it default with 4050.

During the prepare for `start sandbox` phase, this commit
ensures the correct `ProtectionDeviceConfig` is prepared
based on the `GuestProtection` type in a TEE platform.
Specifically, for the TDX platform, this commit sets the
essential parameters within the ProtectionDeviceConfig,
including the TDX ID, firmware path, and the default QGS
port (4050).
This information is then passed to the underlying VMM for
further processing using the existing ResourceManager and
DeviceManager infrastructure.

This patch introduces TdxConfig with key fields, firmare,
qgs_port, mrconfigid, and other useful things. With this config,
a new ProtectionDeviceConfig type `Tdx(TdxConfig)` is added.
With this new type supported, we finally add tdx protection device
into the cmdline to launch a TDX-based CVM.

This commit introduces the `tdx-guest` designed to facilitate
the launch of CVMs leveraging Intel's TDX.
Launching a TDX-based CVM requires various properties, including
`quote-generation-socket`, and `mrconfigid`,`sept-ve-disable` .etc.
(1) The `quote-generation-socket` property is added to the
`tdx-guest` object, which is of type `SocketAddress`, specifies the
address of the Quote Generation Service (QGS).
(2) The `mrconfigid` property, representing the SHA384 hash
for non-owner-defined configurations of the guest TD, is introduced as a
runtime or OS configuration parameter.
(3) And the `sept-ve-disable` property allows control over whether
EPT violation conversions to #VE exceptions are disabled when the guest
TD accesses PENDING pages.
With the introduction of the `tdx-guest` object and its associated
properties, launching TDX-based CVMs is now supported. For example, a
TDX guest can be configured via the command line as follows:
```shell
-object {"qom-type":"tdx-guest", "id":"tdx", "sept-ve-disable":true,\
"mrconfigid":"vHswGkzG4B3Kikg96sLQ5vPCYx4AtuB4Ubfzz9UOXvZtCGat8b8ok7Ubz4AxDDHh",\
"quote-generation-socket":{"type":"vsock","cid":"2","port":"4050"} \
-machine q35,accel=kvm,confidential-guest-support=tdx

across system components:
(1) Add serde serialization/deserialization with standardized
field naming convention.
(2) Enforce string-based port/cid and unix/path representation
for protocol compatibility.

This completely eliminates the Azure secret from the repo, following the below
guidance:
https://docs.github.com/en/actions/security-for-github-actions/security-hardening-your-deployments/configuring-openid-connect-in-azure
The federated identity is scoped to the `ci` environment, meaning:
* I had to specify this environment in some YAMLs. I don't believe there's any
downside to this.
* As previously, the CI works seamlessly both from PRs and in the manual
workflow.
I also deleted the tools/packaging/kata-deploy/action folder as it doesn't seem
to be used anymore, and it contains a reference to the secret.

Instead of looping over the users per group and parsing passwd for each
user, we can do the reverse lookup uid->user up front and then compare
the names directly. This has the nice side-effect of silencing warnings
about non-existent users mentioned in /etc/group, which is not relevant
for policy decisions.

containerd does not automatically add groups to the list of additional
GIDs when the groups have the same name as the user:
https://github.com/containerd/containerd/blob/f482992/pkg/oci/spec_opts.go#L852-L854
This is a bug and should be corrected, but it has been present since at
least 1.6.0 and thus affects almost all containerd deployments in
existence. Thus, we adopt the same behavior and ignore groups with the
same name as the user when calculating additional GIDs.
