Brad Fitzpatrick e062b46984 tstest/natlab, .github/workflows: add opt-in natlab CI workflow
The natlab vmtest suite (tstest/natlab/vmtest) and the integration nat
tests are gated behind --run-vm-tests because they need KVM and are
slow. Until now nothing in CI exercised them apart from a single
canary TestEasyEasy run on every PR.

Add .github/workflows/natlab-test.yml that runs the full opt-in suite
on demand (workflow_dispatch), on PRs labeled "natlab", and on main
every 12 hours via cron. The workflow has two phases:

  - "prepare" builds the gokrazy VM image, downloads the Ubuntu and
    FreeBSD cloud images once via the new natlabprep tool, and emits
    a dynamic JSON matrix of every TestX function it finds in the two
    opt-in packages.
  - "test" is a per-test matrix that depends on prepare. Each matrix
    job restores the shared caches and runs a single test, so adding
    a new TestFoo is automatically picked up on the next run without
    any workflow edits.

Rename the existing natlab-integrationtest.yml to natlab-basic.yml
since it's the small smoke variant (just TestEasyEasy on every PR);
the new natlab-test.yml is the bigger suite. The job inside is
renamed to EasyEasy for the same reason.

Move the macOS arm64 host check from vmtest.Env.Start into
vmtest.Env.AddNode so a test that adds a vmtest.MacOS node skips
immediately on a non-macOS host, and add an explicit
skipIfNotMacOSArm64 helper at the top of the two macOS-only tests
so the platform requirement is obvious to readers.

Quiet the takeAgentConnOne miss log in tstest/natlab/vnet by default
(it was the overwhelming majority of bytes in CI logs, with no signal
in healthy runs) and replace it with a periodic "still waiting" line
that only fires after 10s, so a truly stuck agent connection still
surfaces.

Updates #13038
