* Mask console-getty.service to prevent multi-distro failures (#13595)
When multiple WSL distros run concurrently, /dev/tty devices are shared
at the VM level. The second distro's console-getty.service fails because
the tty is already held by the first, causing systemd to report failed
units and triggering user@UID.service failures.
Mask console-getty.service during WSL systemd unit generation, similar
to the existing masking of networkd-wait-online. This service provides
no value in WSL since users don't connect to the underlying tty.
Fixes#13595

* Add /attachdebugger option to automatically launch WinDbgX for test debugging
When /attachdebugger is passed to test.bat, run-tests.ps1 now:
- Starts te.exe with /waitfordebugger in the background
- Polls for the TE.ProcessHost.exe child process via WMI
- Launches WinDbgX attached directly to the test host PID
- With /inproc, attaches to TE.exe itself instead
This replaces the manual workflow of running /waitfordebugger, reading
the PID from the output, and launching WinDbgX separately.

* run-tests: use /inproc with /attachdebugger, simplify exit
Per review feedback from @OneBlue:
- Add /inproc when /attachdebugger is set so WinDbgX attaches
directly to TE.exe instead of polling for TE.ProcessHost.exe
- Simplify exit to pass through TE.exe exit code directly

* docs: update /attachdebugger to reflect /inproc behavior
The script now always adds /inproc, so update the README to match:
WinDbgX attaches directly to TE.exe, no ProcessHost polling.

* Refactor: trim unnecessary DLL deps from COMMON_LINK_LIBRARIES
- Split MSI/Wintrust install functions from wslutil.cpp into install.cpp
- Remove MI.lib, wsldeps.lib, msi.lib, Wintrust.lib, computecore.lib,
computenetwork.lib, Iphlpapi.lib from COMMON_LINK_LIBRARIES
- Add per-target MSI_LINK_LIBRARIES, HCS_LINK_LIBRARIES, SERVICE_LINK_LIBRARIES
- Delay-load msi.dll and WINTRUST.dll for wsl.exe and wslg.exe
- Result: wslhost, wslrelay, wslcsdk, testplugin lose msi/wintrust startup imports;
wsl.exe and wslg.exe defer msi/wintrust loading until actually needed;
wslservice is the only target that imports computecore/computenetwork/Iphlpapi
* minor fixes to install.cpp that were caught during PR
* move to wsl::windows::common::install namespace

- Allow VirtioProxy to keep EnableDnsTunneling=true in config, but clear
socket-specific options (BestEffortDnsParsing, DnsTunnelingIpAddress)
- Suppress dedicated DNS tunneling hvsocket for VirtioProxy; tunneling
is handled through the VirtioNetworking device host instead
- Set DnsTunneling flag on VirtioNetworkingFlags so the device host
knows to tunnel DNS
- Expand SWIOTLB kernel cmdline to cover VirtioFs and VirtioProxy
- Bump DeviceHost package to 1.1.39-0
- Add VirtioProxy DNS test coverage for tunneling on/off
- Skip GuestPortIsReleasedV6 on Windows 10

* Ship initrd.img in MSI using build-time generation via tar.exe
Replace the install-time CreateInitrd/RemoveInitrd custom actions with a
build-time step that generates initrd.img using the Windows built-in
tar.exe (libarchive/bsdtar) and ships it directly in the MSI.
The install-time approach had a race condition: wsl.exe could launch
before the CreateInitrd custom action completed, causing
ERROR_FILE_NOT_FOUND for initrd.img.
Changes:
- Add CMake custom command to generate initrd.img via tar.exe --format=newc
- Add initrd.img as a regular file in the MSI tools component
- Remove CreateInitrd/RemoveInitrd custom actions from WiX, DllMain,
and wslinstall.def
- Remove CreateCpioInitrd helper and its tests (no longer needed)
- Update pipeline build targets to build initramfs instead of init
* pr feedback

* switch to using a powershell script instead of tar.exe

* Mask NetworkManager-wait-online.service during boot
Fixes#13772. Similar to PR #13611, this masks NetworkManager-wait-online.service to prevent 60-second timeouts during boot since WSL interfaces are unmanaged by NetworkManager. Also added the service to the discouraged units list in validate-modern.py and added a unit test.
