Disable AVX10 as unnecessary as AVX10_LEVEL is better suited for
checking AVX10 compatibility. There is not yet any hardware with the
feature so disabling it shouldn't cause problems for users.
Add new cpuid label "feature.node.kubernetes.io/cpu-cpuid.AVX10_VERSION"
that advertises the supported version of AVX10 vector ISA.
Correspondingly, the patch adds AVX10_VERSION to the "cpu.cpuid" feature
for NodeFeatureRules to consume.
This makes cpu.cpuid on amd64 architecture a "multi-type" feature in
that it contains "flags" and potentially also "attributes" (the only
cpuid attribute so far is the AVX10_VERSION).
First, fix a typo s/sex/sev/. Second, these features are not advertised
as node labels but only as "raw" features available for consumption in
NodeFeatureRules.
Drop the deprecated cpu-sgx.enabled and cpu-se.enabled labels and the
corresponding "raw" features. These have been replaced by
cpu-security.sgx.enabled and cpu-security.se.enabled.
NFD already has the capability to discover whether baremetal / host
machines support Intel TDX. Now, the next step is to add support for
discovering whether a node is TDX protected (as in, a virtual machine
started using Intel TDX).
In order to do so, we've decided to go for a new `cpu-security.tdx`
property, called `protected` (`cpu-security.tdx.protected`).

Commit bfbc47f55e added a lot of those and
this patch tries to cover all that we missed there. Having .md suffixes
in references to internal files makes it convenient to browse the
document locally, just as text files as the references work correctly.
This patch add SEV ASIDs and the related (but distinct) SEV Encrypted State
(SEV-ES) IDs as two quantities to be exposed via extended resources.
In a kernel built with CONFIG_CGROUP_MISC on a suitably equipped AMD CPU, the
root control group will have a misc.capacity file that shows the number of
available IDs in each category.
The added extended resources are:
- sev.asids
- sev.encrypted_state_ids

Document built-in RDT labels to be deprecated and removed in a future
release. The plan is that the default built-in RDT labels would not be
created anymore, but the RDT features would still be available for
NodeFeatureRules to consume.
The RDT labels are not very useful (they don't e.g indicate if the
features are really enabled in kernel or if the resctrlfs is mounted).
The total amount of keys that can be used on a specific TDX system is
exposed via the cgroups misc.capacity. See:
```
$ cat /sys/fs/cgroup/misc.capacity
tdx 31
```
The first step to properly manage the amount of keys present in a node
is exposing it via the NFD, and that's exactly what this commit does.
An example of how it ends up being exposed via the NFD:
```
$ kubectl get node 984fee00befb.jf.intel.com -o jsonpath='{.metadata.labels}' | jq | grep tdx.total_keys
"feature.node.kubernetes.io/cpu-security.tdx.total_keys": "31",
```

Bump cpuid version to v2.2.4 in the go.mod so that WRMSRNS (
Non-Serializing Write to Model Specific Register) and MSRLIST
(Read/Write List of Model Specific Registers) instructions are
detectable.

Bump cpuid to v2.2.3 which adds support for detecting Intel Sierra
Forest instructions like AVXIFMA, AVXNECONVERT, AVXVNNIINT8 and
CMPCCXADD.

Drop the following flags that were deprecated already in v0.8.0:
-sleep-interval (replaced by core.sleepInterval config file option)
-label-whitelist (replaced by core.labelWhiteList config file option)
-sources (replaced by -label-sources flag)
Introduce two main sections "Deployment" and "Usage" and move "Developer
guide" to the top level, too. In particular, split the huge
deployment-and-usage file into multiple parts under the new main
sections. Move customization guide from "Advanced" to "Usage".
This patch also renames "Advanced" to "Reference" as only that is left
there is reference documentation.
