Brad Fitzpatrick 383120c534 ipn/ipnlocal: don't run portlist code unless service collection is on
We were selectively uploading it, but we were still gathering it,
which can be a waste of CPU.

Also remove a bunch of complexity that I don't think matters anymore.

And add an envknob to force service collection off on a single node,
even if the tailnet policy permits it.

Fixes #13463
