drm/xe/uapi: Remove support for persistent exec_queues

Persistent exec_queues delays explicit destruction of exec_queues until they are done executing, but destruction on process exit is still immediate. It turns out no UMD is relying on this functionality, so remove it. If there turns out to be a use-case in the future, let's re-add. Persistent exec_queues were never used for LR VMs v2: - Don't add an "UNUSED" define for the missing property (Lucas, Rodrigo) v3: - Remove the remaining struct xe_exec_queue::persistent state (Niranjana, Lucas)
