anv: Fix geometry flickering issue when compute and 3D passes are combined

Call flush_pipeline_select_3d in CmdBeginRendering() to emit a dummy MEDIA_VFE_STATE
before switching from GPGPU to 3D.

Original commit with the fix:
bc612536 ("anv: Emit a dummy MEDIA_VFE_STATE before switching from GPGPU to 3D")
