Add blob resource support to the vhost-user-gpu device, enabling Vulkan pass-through via Venus with a vhost-user backend such as vhost-device-gpu.
Patches 1-2 forward the RESOURCE_BLOB and CONTEXT_INIT feature flags from the backend to the guest and register a shared memory region for SHMEM_MAP/UNMAP operations. Patch 3 fixes a deadlock that occurs when the memory region transaction commit (needed so the KVM slot exists before the guest accesses the mapped region) triggers ADD_MEM_REG back to the backend while it is still blocked waiting for the SHMEM_MAP reply.
