Rename kube/{types,client,api} -> kube/{kubetypes,kubeclient,kubeapi}
so that we don't need to rename the package on each import to
convey that it's kubernetes specific.

Further split kube package into kube/{client,api,types}. This is so that
consumers who only need constants/static types don't have to import
the client and api bits.

cmd/containerboot,kube,ipn/store/kubestore: allow interactive login and empty state Secrets, check perms
* Allow users to pre-create empty state Secrets
* Add a fake internal kube client, test functionality that has dependencies on kube client operations.
* Fix an issue where interactive login was not allowed in an edge case where state Secret does not exist
* Make the CheckSecretPermissions method report whether we have permissions to create/patch a Secret if it's determined that these operations will be needed

We would call Update on the secret, but that was racey and would occasionaly
fail. Instead use patch whenever we can.
Fixes errors like

For stores like k8s secrets we need to dial out to the k8s API as though Tailscale
wasn't running. The issue currently only manifests when you try to use an exit node
while running inside a k8s cluster and are trying to use Kubernetes secrets as the
backing store.
This doesn't address cmd/containerboot, which I'll do in a follow up.

Kubernetes doesn't allow slashes as keys in secrets, replace them with "__".
This shows up in the kubernetes-operator now that tsnet sets resets the ServeConfig
at startup.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Also move KubeStore and MemStore into their own package.
RELNOTE: tsnet now supports providing a custom ipn.StateStore.
