drm/i915/selftests: Test vm isolation
The vm of two contexts are supposed to be independent, such that a stray
write by one cannot be detected by another. Normally the GTT is filled
explicitly by userspace, but the space in between objects is filled with
a scratch page -- and that scratch page should not be able to form an
inter-context backchannel.
