In v1.78, we started acquiring the GP lock when reading policy settings. This led to a deadlock during
Tailscale installation via Group Policy Software Installation because the GP engine holds the write lock
for the duration of policy processing, which in turn waits for the installation to complete, which in turn
waits for the service to enter the running state.
In this PR, we prevent the acquisition of GP locks (aka EnterCriticalPolicySection) during service startup
and update the Windows Registry-based util/syspolicy/source.PlatformPolicyStore to handle this failure
gracefully. The GP lock is somewhat optional; it’s safe to read policy settings without it, but acquiring
the lock is recommended when reading multiple values to prevent the Group Policy engine from modifying
settings mid-read and to avoid inconsistent results.

This pulls out the Wake-on-LAN (WoL) code out into its own package
(feature/wakeonlan) that registers itself with various new hooks
around tailscaled.
Then a new build tag (ts_omit_wakeonlan) causes the package to not
even be linked in the binary.
Ohter new packages include:
* feature: to just record which features are loaded. Future:
dependencies between features.
* feature/condregister: the package with all the build tags
that tailscaled, tsnet, and the Tailscale Xcode project
extension can empty (underscore) import to load features
as a function of the defined build tags.
Future commits will move of our "ts_omit_foo" build tags into this
style.

We previously baked in the LetsEncrypt x509 root CA for our tlsdial
package.
This moves that out into a new "bakedroots" package and is now also
shared by ipn/ipnlocal's cert validation code (validCertPEM) that
decides whether it's time to fetch a new cert.
Otherwise, a machine without LetsEncrypt roots locally in its system
roots is unable to use tailscale cert/serve and fetch certs.

I moved the actual rename into separate, GOOS-specific files. On
non-Windows, we do a simple os.Rename. On Windows, we first try
ReplaceFile with a fallback to os.Rename if the target file does
not exist.
ReplaceFile is the recommended way to rename the file in this use case,
as it preserves attributes and ACLs set on the target file.

In this PR, we add a generic views.ValuePointer type that can be used as a view for pointers
to basic types and struct types that do not require deep cloning and do not have corresponding
view types. Its Get/GetOk methods return stack-allocated shallow copies of the underlying value.
We then update the cmd/viewer codegen to produce getters that return either concrete views
when available or ValuePointer views when not, for pointer fields in generated view types.
This allows us to avoid unnecessary allocations compared to returning pointers to newly
allocated shallow copies.

This amends commit b7e48058c8d243adf1ff687e3e92d3fb02b035ea.
That commit broke all documented ways of starting Tailscale on gokrazy:
https://gokrazy.org/packages/tailscale/ — both Option A (tailscale up)
and Option B (tailscale up --auth-key) rely on the tailscale CLI working.
I verified that the tailscale CLI just prints it help when started
without arguments, i.e. it does not stay running and is not restarted.
I verified that the tailscale CLI successfully exits when started with
tailscale up --auth-key, regardless of whether the node has joined
the tailnet yet or not.
I verified that the tailscale CLI successfully waits and exits when
started with tailscale up, as expected.

Move a number of global state vars into the Menu struct, keeping things
better encapsulated. The systray package still relies on its own global
state, so only a single Menu instance can run at a time.
Move a lot of the initialization logic out of onReady, in particular
fetching the latest tailscale state. Instead, populate the state before
calling systray.Run, which fixes a timing issue in GNOME (#14477).
This change also creates a separate bgContext for actions not tied menu
item clicks. Because we have to rebuild the entire menu regularly, we
cancel that context as needed, which can cancel subsequent updateState
calls.
Also exit cleanly on SIGINT and SIGTERM.
