Prevents the VPN startup from hanging for 5 minutes due to a startupbackoff if `wintun.dll` cannot be loaded.Because the `wintun` package doesn't expose an easy `Load() error`method for us, the only way for us to force it to load (without unwantedside effects) is through `wintun.Version()` which doesn't return anerror message.So, we call that function so the `wintun` package loads the DLL andconfigures the logging properly, then we try to load the DLL ourselves.`LoadLibraryEx` will not load the library multiple times and returns areference to the existing library.Closescoder/coder-desktop-windows#24

Cherry-picked fix(vpn): fail early if wintun.dll is not present (#16707)
Prevents the VPN startup from hanging for 5 minutes due to a startup
backoff if
wintun.dllcannot be loaded.Because the
wintunpackage doesn't expose an easyLoad() errormethod for us, the only way for us to force it to load (without unwanted
side effects) is through
wintun.Version()which doesn't return anerror message.
So, we call that function so the
wintunpackage loads the DLL andconfigures the logging properly, then we try to load the DLL ourselves.
LoadLibraryExwill not load the library multiple times and returns areference to the existing library.
