drm/xe: Force EXEC_QUEUE_FLAG_KERNEL for kernel internal VMs

Browse Source 
VMs created without an associated xe_file originate from kernel
contexts and should use kernel exec queues. Ensure such VMs
create bind exec queues with EXEC_QUEUE_FLAG_KERNEL set.
Let's ensure bind exec queues created for kernel VMs are always
marked with EXEC_QUEUE_FLAG_KERNEL.
