On some platforms e.g. ChromeOS the owner hierarchy might not always be
available to us. To avoid stale sealing exceptions later we probe to
confirm it's working rather than rely solely on family indicator status.

Extend Persist with AttestationKey to record a hardware-backed
attestation key for the node's identity.
Add a flag to tailscaled to allow users to control the use of
hardware-backed keys to bind node identity to individual machines.

Extend the client state management to generate a hardware attestation
key if none exists.
Extend MapRequest with HardwareAttestationKey{,Signature} fields that
optionally contain the public component of the hardware attestation key
and a signature of the node's node key using it. This will be used by
control to associate hardware attesation keys with node identities on a
TOFU basis.

RELNOTE=Fix CSRF errors in the client Web UI
Replace gorilla/csrf with a Sec-Fetch-Site based CSRF protection
middleware that falls back to comparing the Host & Origin headers if no
SFS value is passed by the client.
Add an -origin override to the web CLI that allows callers to specify
the origin at which the web UI will be available if it is hosted behind
a reverse proxy or within another application via CGI.

Update proxy-to-grafana to strip any X-Webauth prefixed headers passed
by the client in *every* request, not just those to /login.
/api/ routes will also accept these headers to authenticate users,
necessitating their removal to prevent forgery.

Fix the order of the CSRF handlers (HTTP plaintext context setting,
_then_ enforcement) in the construction of the web UI server. This
resolves false-positive "invalid Origin" 403 exceptions when attempting
to update settings in the web UI.
Add unit test to exercise the CSRF protection failure and success cases
for our web UI configuration.

Refactor the interaction between caller/library when establishing the
HTTP to HTTPS redirects by moving the call to http.Serve into safeweb.
This makes linting for other uses of http.Serve easier without having to
account for false positives created by the old interface.

Updates https://github.com/tailscale/corp/issues/8027
Safeweb is a wrapper around http.Server & tsnet that encodes some
application security defaults.
Safeweb asks developers to split their HTTP routes into two
http.ServeMuxs for serving browser and API-facing endpoints
repsectively. It then wraps these HTTP routes with the
context-appropriate security controls.
safeweb.Server#Serve will serve the HTTP muxes over the provided
listener. Caller are responsible for creating and tearing down their
application's listeners. Applications being served over HTTPS that wish
to implement HTTP redirects can use the Server#HTTPRedirect handler to
do so.

* tsweb: update ServeMux matching to 1.22.0 syntax
Updates #cleanup
Go 1.22.0 introduced the ability to use more expressive routing patterns
that include HTTP method when constructing ServeMux entries.
Applications that attempted to use these patterns in combination with
the old `tsweb.Debugger` would experience a panic as Go would not permit
the use of matching rules with mixed level of specificity. We now
specify the method for each `/debug` handler to prevent
incompatibilities.
