0e7928edce Add new CPUManager policy option for "distribute-cpus-across-numa"
This commit only adds the option to the policy options framework. A
subsequent commit will add the logic to utilize it.

The KEP describing this new option can be found here:

077c0aa1be node: graduate CPUManagerPolicyOptions to beta
We graduate the `CPUManagerPolicyOptions` feature to beta
in the 1.23 cycle, and we add new experimental feature gates
to guard new options which are planned in the 1.23 and in the
following cycles.

We introduce additional feature gate called `CPUManagerPolicyAlphaOptions` and
`CPUManagerPolicyBetaOptions`. The basic idea is to avoid the
cumbersome process of adding a feature gate for each option, and to have
feature gates which track the maturity level of _groups_ of options.
Besides this change, the graduation process, and the process in general,
for adding new policy options is still unchanged.

The `full-pcpus-only` option added in the 1.22 cycle is intentionally
moved into the beta policy options

23abdab2b7 smtalign: propagate policy options to policies
Consume in the static policy the cpu manager policy options from
the cpumanager instance.
Validate in the none policy if any option is given, and fail if so -
this is almost surely a configuration mistake.

Add new cpumanager.Options type to hold the options and translate from
user arguments to flags.
