drm/i915: Mark shadow batch buffers as purgeable
By adding a new exec_entry flag, we cleanly mark the shadow objects
as purgeable after they are on the active list.
v2:
- Move 'shadow_batch_obj->madv = I915_MADV_WILLNEED' inside _get
fnc (danvet, from v4 6/7 feedback)
v3:
- Remove duplicate 'madv = I915_MADV_WILLNEED' (danvet, from v6 4/5)
