[$] A parallel path for GPU restore in CRIU

Description:
The fundamental concept of checkpoint/restore is elegant: capture a
process's state and resurrect it later, perhaps elsewhere. Checkpointing meticulously records a process's memory, open files, CPU state, and more into a
snapshot. Restoration then reconstructs the process from this state. This established technique faces new challenges with GPU-accelerated applications, where low-latency restoration is crucial for fault
tolerance , live migration, and
fast startups. Recently, the restore process for AMD GPUs has been redesigned to
eliminate substantial bottlenecks.
