Set `cpu-security.tdx.enable` to `true` when TDX is avialable and has
been enabled. otherwise it'll be set to `false`.
`/sys/module/kvm_intel/parameters/tdx` presence and content is used to
detect whether a CPU is Intel TDX capable.

Move existing security/trusted-execution related features (i.e. SGX and
SE) under the same "security" feature, deprecating the old features. The
motivation for the change is to keep the source code and user interface
more organized as we experience a constant inflow of similar security
related features. This change will affect the user interface so it is
less painful to do it early on.
New feature labels will be:
feature.node.kubernetes.io/cpu-security.se.enabled
feature.node.kubernetes.io/cpu-security.sgx.enabled
and correspondingly new "cpu.security" feature with "se.enabled" and
"sgx.enabled" elements will be available for custom rules, for example:
- name: "sample sgx rule"
labels:
sgx.sample.feature: "true"
matchFeatures:
- feature: cpu.security
matchExpressions:
"sgx.enabled": {op: IsTrue}
At the same time deprecate old labels "cpu-sgx.enabled" and
"cpu-se.enabled" feature labels and the corresponding features for
custom rules. These will be removed in the future causing an effective
change in NFDs user interface.
