This PR adds a new field to the serve config that can be used to identify which serves are in "foreground mode" and then can also be used to ensure they do not get persisted to disk so that if Tailscaled gets ungracefully shutdown, the reloaded ServeConfig will not have those ports opened.

This PR adds a new field to the ServeConfig which maps
WatchIPNBus session ids to foreground serve configs.
The PR also adds a DeleteForegroundSession method to ensure the config
gets cleaned up on sessions ending.
Note this field is not currently used but will be in follow up work.

This PR adds a SessionID field to the ipn.Notify struct so that
ipn buses can identify a session and register deferred clean up
code in the future. The first use case this is for is to be able to
tie foreground serve configs to a specific watch session and ensure
its clean up when a connection is closed.

The tailscale serve|funnel commands frequently call the LocalBackend's Status
but they never need the peers to be included. This PR changes the call to be
StatusWithoutPeers which should gain a noticeable speed improvement

This PR removes all async functionality from the portlist package
which may be a breaking change for non-tailscale importers. The only
importer within this codebase (LocalBackend) is already using the synchronous
API so no further action needed.

This is a follow up on PR #8172 that adds a synchronous Poll method
which allows for the Poller to be used as a zero value without needing
the constructor. The local backend is also changed to use the new API.
A follow up PR will remove the async functionality from the portlist package.
