drm/i915: Add tracepoints to track a vm during its lifetime
- ppgtt init/release: these tracepoints are useful for observing the
creation and destruction of Full PPGTTs.
- ctx create/free: we can use the ctx_free trace in combination with the
ppgtt_release one to be sure that the ppgtt doesn't stay alive for too
long after the ctx is destroyed. ctx_create is there for simmetry
- switch_mm: important point in the lifetime of the vm
v4: add DOC information
v5: pull the DOC in drm.tmpl
v6: clean ppgtt init/release traces + add ctx create/free and switch_mm
tracepoints (Chris)
v7: drop execlist_submit_context tracepoint
