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.

This adds the ability to "peek" at the value of a SyncValue, so that
it's possible to observe a value without computing this.

This moves NewContainsIPFunc from tsaddr to new ipset package.
And wgengine/filter types gets split into wgengine/filter/filtertype,
so netmap (and thus the CLI, etc) doesn't need to bring in ipset,
bart, etc.
Then add a test making sure the CLI deps don't regress.

NewContainsIPFunc was previously documented as performing poorly if
there were many netip.Prefixes to search over. As such, we never it used it
in such cases.
This updates it to use bart at a certain threshold (over 6 prefixes,
currently), at which point the bart lookup overhead pays off.
This is currently kinda useless because we're not using it. But now we
can and get wins elsewhere. And we can remove the caveat in the docs.

Request ID generation appears prominently in some services cumulative
allocation rate, and while this does not eradicate this issue (the API
still makes UUID objects), it does improve the overhead of this API and
reduce the amount of garbage that it produces.

Also perform minor cleanups on the ctxkey package itself.
Provide guidance on when to use ctxkey.Key[T] over ctxkey.New.
Also, allow for interface kinds because the value wrapping trick
also happens to fix edge cases with interfaces in Go.
