3d83df9bf3 memmod: apply explicit build tags to _32 and _64 files 
Since _32 and _64 aren't valid goarchs, they don't match _GOOS_GOARCH,
and so the existing tags wind up not being restricted to windows-only.
This fixes the problem by adding windows to the tags explicitly. We
could also fix it by calling the files _32_windows or _64_windows, but
that changes the convention with the other single-arch files.

This prevents linking to wintun.dll until it's actually needed, which

3e08b8aee0 wintun: migrate to wintun.dll API 
Rather than having every application using Wintun driver reinvent the
wheel, the Wintun device/adapter/interface management has been moved
from wireguard-go to wintun.dll deployed with Wintun itself.

fdba6c183a wintun: make remaining HWID comparisons case insensitive 
c85e4a410f introduced preliminary HWID
checking to speed up Wintun adapter enumeration. However, all HWID are
case insensitive by Windows convention.

Furthermore, a device might have multiple HWIDs. When DevInfo's
DeviceRegistryProperty(SPDRP_HARDWAREID) method returns []string, all
strings returned should be checked against given hardware ID.

This issue was discovered when researching Wintun and wireguard-go on
Windows 10 ARM64. The Wintun adapter was created using devcon.exe
utility with "wintun" hardware ID, causing wireguard-go fail to
enumerate the adapter properly.

7305b4ce93 wintun: upgrade deleting all interfaces and make it reusable 
DeleteAllInterfaces() didn't check if SPDRP_DEVICEDESC == "WireGuard
Tunnel". It deleted _all_ Wintun adapters, not just WireGuard's.

Furthermore, the DeleteAllInterfaces() was upgraded into a new function
called DeleteMatchingInterfaces() for selectively deletion. This will
be used by WireGuard to clean stale Wintun adapters.
