In some configurations, user explicitly do not want to store
tailscale state in k8s secrets, because doing that leads to
some annoying permission issues with sidecar containers.
With this change, TS_KUBE_SECRET="" and TS_STATE_DIR=/foo
will force storage to file when running in kubernetes.
Fixes#6704.

(cherry picked from commit af3127711a)
We would replace the existing real implementation of nettype.PacketConn
with a blockForeverConn, but that violates the contract of atomic.Value
(where the type cannot change). Fix by switching to a pointer value
(atomic.Pointer[nettype.PacketConn]).
A longstanding issue, but became more prevalent when we started binding
connections to interfaces on macOS and iOS (#6566), which could lead to
the bind call failing if the interface was no longer available.

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.

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.
This reverts commit e0cadc5496.
