Shintaro Kawamura 37f8a7da56 swap: use named memfd for staging memory ... ARCVM tracks its memory usage by monitoring the process group shared memory usage `Platform.Memory.ARC.Shmem`. The staging memory should be a shared memory not a private anonymous memory. The staging memory in Region originally does not need to be `Option` because leaked memory on the staging memory is removed when vmm-swap is disabled. Rather it has introduced useless complexity to the codebase.
