appc,*: publish events for route updates and storage (#17392)
Add and wire up event publishers for these two event types in the AppConnector.
Nothing currently subscribes to them, so this is harmless. Subscribers for
these events will be added in a near-future commit.

As part of this, move the appc.RouteInfo type to the types/appctype package.
It does not contain any package-specific details from appc. Beside it, add
appctype.RouteUpdate to carry route update event state, likewise not specific
to appc.  Update all usage of the appc.* types throughout to use appctype.*
instead, and update depaware files to reflect these changes.

Add a Close method to the AppConnector to make sure the client gets cleaned up
when the connector is dropped (we re-create connectors).

Update the unit tests in the appc package to also check the events published
alongside calls to the RouteAdvertiser.

For now the tests still rely on the RouteAdvertiser for correctness; this is OK
for now as the two methods are always performed together.  In the near future,
we need to rework the tests so not require that, but that will require building
some more test fixtures that we can handle separately.

892f8a9582 various: allow tailscaled shutdown via LocalAPI
A customer wants to allow their employees to restart tailscaled at will, when access rights and MDM policy allow it,
as a way to fully reset client state and re-create the tunnel in case of connectivity issues.

On Windows, the main tailscaled process runs as a child of a service process. The service restarts the child
when it exits (or crashes) until the service itself is stopped. Regular (non-admin) users can't stop the service,
and allowing them to do so isn't ideal, especially in managed or multi-user environments.

In this PR, we add a LocalAPI endpoint that instructs ipnserver.Server, and by extension the tailscaled process,
to shut down. The service then restarts the child tailscaled. Shutting down tailscaled requires LocalAPI write access
and an enabled policy setting.

db34cdcfe7 cmd/tailscale/cli: add a risk message about rp_filter
We already present a health warning about this, but it is easy to miss
on a server when blackholing traffic makes it unreachable.

In addition to a health warning, present a risk message when exit node
is enabled.

Example:

```
$ tailscale up --exit-node=lizard
The following issues on your machine will likely make usage of exit nodes impossible:
- interface "ens4" has strict reverse-path filtering enabled
- interface "tailscale0" has strict reverse-path filtering enabled
Please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310
To skip this warning, use --accept-risk=linux-strict-rp-filter
$
```
