wgengine/magicsock,ipn: allow setting static node endpoints via tailscaled config file.
Adds a new StaticEndpoints field to tailscaled config
that can be used to statically configure the endpoints
that the node advertizes. This field will replace
TS_DEBUG_PRETENDPOINTS env var that can be used to achieve the same.
Additionally adds some functionality that ensures that endpoints
are updated when configfile is reloaded.
Also, refactor configuring/reconfiguring components to use the
same functionality when configfile is parsed the first time or
subsequent times (after reload). Previously a configfile reload
did not result in resetting of prefs. Now it does- but does not yet
tell the relevant components to consume the new prefs. This is to
be done in a follow-up.

Turn off stateful filtering for egress proxies to allow cluster
traffic to be forwarded to tailnet.
Allow configuring stateful filter via tailscaled config file.
Deprecate EXPERIMENTAL_TS_CONFIGFILE_PATH env var and introduce a new
TS_EXPERIMENTAL_VERSIONED_CONFIG env var that can be used to provide
containerboot a directory that should contain one or more
tailscaled config files named cap-<tailscaled-cap-version>.hujson.
Containerboot will pick the one with the newest capability version
that is not newer than its current capability version.
Proxies with this change will not work with older Tailscale
Kubernetes operator versions - users must ensure that
the deployed operator is at the same version or newer (up to
4 version skew) than the proxies.

Some fields if `ipn.Prefs` are structs. `ipn.MaskedPrefs` has a single
level of boolean `*Set` flags, which doesn't map well to nested structs
within `ipn.Prefs`.
Change `MaskedPrefs` and `ApplyEdits` to support `FooSet` struct fields
that map to a nested struct of `ipn.Prefs` like `AutoUpdates`. Each
struct field in `MaskedPrefs` is just a bundle of more `Set` bool fields
or other structs. This allows you to have a `Set` flag for any
arbitrarily-nested field of `ipn.Prefs`.
Also, make `ApplyEdits` match fields between `Prefs` and `MaskedPrefs`
by name instead of order, to make it a bit less finicky. It's probably
slower but `ipn.ApplyEdits` should not be in any hot path.
As a result, `AutoUpdate.Check` and `AutoUpdate.Apply` fields don't
clobber each other when set individually.

This is not currently exposed as a user-settable preference through
`tailscale up` or `tailscale set`. Instead, the preference is set when
turning the web client on and off via localapi. In a subsequent commit,
the pref will be used to automatically start the web client on startup
when appropriate.
