c163b2a3f1 util/winutil, util/winutil/vss: remove winrestore and vss as they are unnecessary.
I wrote this code way back at the beginning of my tenure at Tailscale when we
had concerns about needing to restore deleted machine keys from backups.

We never ended up using this functionality, and the code is now getting in the
way, so we might as well remove it.

net/dns{., resolver}: time out DNS queries after 10 seconds (#4690)
Fixes https://github.com/tailscale/corp/issues/5198

The upstream forwarder will block indefinitely on `udpconn.ReadFrom` if no
reply is recieved, due to the lack of deadline on the connection object.

There still isn't a deadline on the connection object, but the automatic closing
of the context on deadline expiry will close the connection via `closeOnCtxDone`,
unblocking the read and resulting in a normal teardown.

words: after a Series of discussions, Bees should be included (#4606)
There has been a lot of talk about Bees at Tailscale recently, and
naturally, with it being Tailscale, we thought to ourselves:

Do Bees have a tail and/or scales?

Tailscale has a long track record of scientific rigor around the
validity of the inclusions on the tails and scales list, and this time
will be no exception.

Our research has found that Bees, in particular the Honey Bee, produces
wax scales on their abdomens and thus should be included. As for tails;

'Stabby-tails' - Tailscale Employee, 2022

No further justification needed, it will be included.

This change includes Bee in both tails.txt and scales.txt.

c60cbca371 control/controlclient: store netinfo and hostinfo separately
Currently, when SetNetInfo is called it sets the value on
hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the
hostinfo field which may mean it also clears out the NetInfo it had just
received.
This commit stores NetInfo separately and combines it into Hostinfo as
needed so that control is always notified of the latest values.

Also, remove unused copies of Hostinfo from ipn.Status and
controlclient.Auto.
