windows: fix build without --features=balloon

Add the minimal cfg checks to let the Windows target build without
--features=balloon enabled. This doesn't fully guard all uses of balloon
related types, just enough to make it compile, since it's intertwined
with other features (e.g. "kiwi").

BUG=None
TEST=cargo build --no-default-features

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
