drm/i915: Add i915_gem_context_is_full_ppgtt
And use it anywhere we have open-coded checks for ctx->vm that really
only check for full ppgtt.
Plus for paranoia add a GEM_BUG_ON that checks it's really only set
when we have full ppgtt, just in case. gem_context->vm is different
since it's NULL in ggtt mode, unlike intel_context->vm or gt->vm,
which is always set.
v2: 0day found a testcase that I missed.
v3: Repaint shed (Jon, Tvrtko)
