feat(host/windows): PUNKTFUNK_NO_WGC — force single-process DDA everywhere

Browse Source 
A single test flag to bring up / validate DDA on its own and as the base for the
secure-desktop work. When set it (1) skips WGC in capture_virtual_output (forces
dxgi::DuplCapturer, same as PUNKTFUNK_CAPTURE=dda) and (2) makes should_use_helper
return false, so even a SYSTEM host bypasses the two-process WGC relay and captures
in-process with one DDA capturer for both the normal AND the secure desktop —
Apollo's model. All the WGC / relay code stays compiled; unset the flag to restore.
