cmd/{k8s-operator,k8s-proxy}: add kube-apiserver ProxyGroup type (#16266)
Adds a new k8s-proxy command to convert operator's in-process proxy to
a separately deployable type of ProxyGroup: kube-apiserver. k8s-proxy
reads in a new config file written by the operator, modelled on tailscaled's
conffile but with some modifications to ensure multiple versions of the
config can co-exist within a file. This should make it much easier to
support reading that config file from a Kube Secret with a stable file name.

To avoid needing to give the operator ClusterRole{,Binding} permissions,
the helm chart now optionally deploys a new static ServiceAccount for
the API Server proxy to use if in auth mode.

Proxies deployed by kube-apiserver ProxyGroups currently work the same as
the operator's in-process proxy. They do not yet leverage Tailscale Services
for presenting a single HA DNS name.

Updates #13358
