drm/i915: Make GEM contexts track DRM clients
Make GEM contexts keep a reference to i915_drm_client for the whole of
of their lifetime which will come handy in following patches.
v2: Don't bother supporting selftests contexts from debugfs. (Chris)
v3 (Lucas): Finish constructing ctx before adding it to the list
v4 (Ram): Rebase.
v5: Trivial rebase for proto ctx changes.
v6: Rebase after clients no longer track name and pid.
