Reland "swap: suspend device processes using SIGSTOP signal" origin: https://chromium-review.googlesource.com/c/crosvm/crosvm/+/3932497 ProcessesGuard stops all the crosvm processes except the caller process using SIGSTOP signal because we must guarantee that no one changes the guest memory contents while vmm-swap out. This is a short term solution and will be replaced with device suspension feature later.
