Add an xe_vm subtest that oversubscribes VRAM and issues
concurrent binds into a single VM (scratch-page mode) to
reproduce the dma-resv/bind race found under memory pressure.
Prior coverage lacked any case that combined multi-process bind
pressure with VRAM oversubscription, so bind/submit could
panic (NULL deref in xe_pt_stage_bind) instead of failing cleanly.
The new test expects successful completion or ENOMEM/EDEADLK.
