Enable long path support on Windows bots
By default, our Windows bots don't have long path support enabled and
thus, are limited to paths with a maximum of 260 characters. This breaks
some tooling that relies on files with longer paths; for example, some
parts of the Windows SDK -- in particular .winmd files under the
SDK's References directory, which we make use of while generating WinRT
header files with the cppwinrt tool.
