We were previously only doing this for tailscaled-on-Darwin, but it also
appears to help on iOS. Otherwise, when we rebind magicsock UDP
connections after a cellular -> WiFi interface change they still keep
using cellular one.
To do this correctly when using exit nodes, we need to exclude the
Tailscale interface when getting the default route, otherwise packets
cannot leave the tunnel. There are native macOS/iOS APIs that we can
use to do this, so we allow those clients to override the implementation
of DefaultRouteInterfaceIndex.
Updates #6565, may also help with #5156

renamed from `useNetstack` to `onlyNetstack` which is 1 letter more but
more descriptive because we always have netstack enabled and `useNetstack`
doesn't convey what it is supposed to be used for. e.g. we always use
netstack for Tailscale SSH.
Also renamed shouldWrapNetstack to handleSubnetsInNetstack as it was only used
to configure subnet routing via netstack.

The peerapi IPv6 listener has a nil listener.
But we didn't need the listener's address anyway, so don't
try to use it.

Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With
this change:
- Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded)
require either the WIP envknob or CapabilityTailnetLockAlpha.
- Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the
envknob / capability.
- Auxillary commands (ie: changing tka keys) require TKA to be initialized.
The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being
sent the capability or setting the envknob on tailscaled yourself.
I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock().

When running `tailscale web` as a standalone process,
it was necessary to send auth requests to QTS using
localhost to avoid hitting the proxy recursively.
However running `tailscale web` as a process means it is
consuming RAM all the time even when it isn't actively
doing anything.
After switching back to the `tailscale web` CGI mode, we
don't need to specifically use localhost for QNAP auth.

We want users to have the freedom to start tailscaled with `-no-logs-no-support`,
but that is obviously in direct conflict with tailnets that have network logging
enabled.
When we detect that condition, we record the issue in health, notify the client,
set WantRunning=false, and bail.
We clear the item in health when a profile switch occurs, since it is a
per-tailnet condition that should not propagate across profiles.

This adds an envknob to make testing async startup more reproducible.
We want the Windows GUI to behave well when wintun is not (or it's
doing its initial slow driver installation), but during testing it's often
too fast to see that it's working. This lets it be slowed down.
