runtime-rs: Support cold plug of block devices via virtio-blk for Qemu

Browse Source 
Two key important scenarios:
(1) Support `virtio-blk-pci` cold plug capability for confidential guests
instead of nvdimm device in CVM due to security constraints in CoCo cases.
(2) Push initdata payload into compressed raw block device and insert it
in CVM through `virtio-blk-pci` cold plug mechanism.

Fixes #11341
