We update profileManager to allow registering a single state (profile+prefs) change hook.
This is to invert the dependency between the profileManager and the LocalBackend, so that
instead of LocalBackend asking profileManager for the state, we can have profileManager
call LocalBackend when the state changes.
We also update feature.Hook with a new (*feature.Hook).GetOk method to avoid calling both
IsSet and Get.

This further minimizes the number of places where the profile manager updates the current profile and prefs.
We also document a scenario where an implicit profile switch can occur.
We should be able to address it after (partially?) inverting the dependency between
LocalBackend and profileManager, so that profileManager notifies LocalBackend
of profile changes instead of the other way around.

The previous strategy assumed clients maintained adequate state to
understand the relationship between endpoint allocation and the server
it was allocated on.
magicsock will not have awareness of the server's disco key
pre-allocation, it only understands peerAPI address at this point. The
second client to allocate on the same server could trigger
re-allocation, breaking a functional relay server endpoint.
If magicsock needs to force reallocation we can add opt-in behaviors
for this later.

We had an ordered set type (set.Slice) already but we occasionally want
to do the same thing with a map, preserving the order things were added,
so add that too, as mapsx.OrderedMap[K, V], and then use in ipnext.

Now that 25c4dc5fd70 removed unregistering hooks and made them into
slices, just expose the slices and remove the setter funcs.
This removes boilerplate ceremony around adding new hooks.
This does export the hooks and make them mutable at runtime in theory,
but that'd be a data race. If we really wanted to lock it down in the
future we could make the feature.Hooks slice type be an opaque struct
with an All() iterator and a "frozen" bool and we could freeze all the
hooks after init. But that doesn't seem worth it.
This means that hook registration is also now all in one place, rather
than being mixed into ProfilesService vs ipnext.Host vs FooService vs
BarService. I view that as a feature. When we have a ton of hooks and
the list is long, then we can rearrange the fields in the Hooks struct
as needed, or make sub-structs, or big comments.

The typical way to implement union types in Go
is to use an interface where the set of types is limited.
However, there historically has been poor support
in v1 "encoding/json" with interface types where
you can marshal such values, but fail to unmarshal them
since type information about the concrete type is lost.
The MakeInterfaceCoders function constructs custom
marshal/unmarshal functions such that the type name
is encoded in the JSON representation.
The set of valid concrete types for an interface
must be statically specified for this to function.

This adds support for signing with a Google Cloud hosted key.
The key should be an RSA key with protection level `HSM` and that uses PSS padding and a SHA256 digest.

When an event bus is plumbed in, use it to subscribe and react to port mapping
updates instead of using the client's callback mechanism. For now, the callback
remains available as a fallback when an event bus is not provided.

When an event bus is configured publish an event each time a new port mapping
is updated. Publication is unconditional and occurs prior to calling any
callback that is registered. For now, the callback is still fired in a separate
goroutine as before -- later, those callbacks should become subscriptions to
the published event.
For now, the event type is defined as a new type here in the package. We will
want to move it to a more central package when there are subscribers. The event
wrapper is effectively a subset of the data exported by the internal mapping
interface, but on a concrete struct so the bus plumbing can inspect it.

In preparation for adding more parameters (and later, moving some away), rework
the portmapper constructor to accept its arguments on a Config struct rather
than positionally.
This is a breaking change to the function signature, but one that is very easy
to update, and a search of GitHub reveals only six instances of usage outside
clones and forks of Tailscale itself, that are not direct copies of the code
fixed up here.
While we could stub in another constructor, I think it is safe to let those
folks do the update in-place, since their usage is already affected by other
changes we can't test for anyway.

This feature is "registered" as an ipnlocal.Extension, and
conditionally linked depending on GOOS and ts_omit_relayserver build
tag.
The feature is not linked on iOS in attempt to limit the impact to
binary size and resulting effect of pushing up against NetworkExtension
limits. Eventually we will want to support the relay server on iOS,
specifically on the Apple TV. Apple TVs are well-fitted to act as
underlay relay servers as they are effectively always-on servers.
This skeleton begins to tie a PeerAPI endpoint to a net/udprelay.Server.
The PeerAPI endpoint is currently no-op as
extension.shouldRunRelayServer() always returns false. Follow-up commits
will implement extension.shouldRunRelayServer().

https://github.com/tailscale/tailscale/pull/15395 changed the logic to
skip `EditPrefs` when the platform doesn't support auto-updates. But the
old logic would only fail `EditPrefs` if the auto-update value was
`true`. If it was `false`, `EditPrefs` would succeed and store `false`
in prefs. The new logic will keep the value `unset` even if the tailnet
default is `false`.

In this PR, we enable extensions to track changes in the current prefs. These changes can result from a profile switch
or from the user or system modifying the current profile’s prefs. Since some extensions may want to distinguish between
the two events, while others may treat them similarly, we rename the existing profile-change callback to become
a profile-state-change callback and invoke it whenever the current profile or its preferences change. Extensions can still
use the sameNode parameter to distinguish between situations where the profile information, including its preferences,
has been updated but still represents the same tailnet node, and situations where a switch to a different profile has been made.
Having dedicated prefs-change callbacks is being considered, but currently seems redundant. A single profile-state-change callback
is easier to maintain. We’ll revisit the idea of adding a separate callback as we progress on extracting existing features from LocalBackend,
but the conversion to a profile-state-change callback is intended to be permanent.
Finally, we let extensions retrieve the current prefs or profile state (profile info + prefs) at any time using the new
CurrentProfileState and CurrentPrefs methods. We also simplify the NewControlClientCallback signature to exclude
profile prefs. It’s optional, and extensions can retrieve the current prefs themselves if needed.
