The prefix is a signal to tsweb to treat this as a gauge metric when
generating the Prometheus version.

We were marking them as gauges, but they are only ever incremented,
thus counter is more appropriate.

The Mac client was using it, but it had the effect of the `RouteAll`
("Use Tailscale subnets") pref always being enabled at startup,
regardless of the persisted value.
enforceDefaults was added to handle cases from ~2 years ago where
we ended up with persisted `"RouteAll": false` values in the keychain,
but that should no longer be a concern. New users will get the default
of it being enabled via `NewPrefs`.
There will be a corresponding Mac client change to stop passing in
enforceDefaults.
For #3962
