Localize "General" in OutputWindowHelper

WindowsAppSDK/dev/VSIX/Shared/OutputWindowHelper.cs

Line 32 in a4dfca2

hr = outputWindow.CreatePane(ref guidGeneral, "General", 1, 1);

This code path likely won't be hit very often, as VS should be able to create the general pane of the output window before this. But VS does localize output pane names, so this string should be moved to a localized resource.
