zink: always unset vertex shader variant key data when changing last vertex stage

Browse source 
ensure that vertex key data is always zeroed when changing last stage since it will
be updated before draw anyway and can only cause problems if left alone here

fixes the following caselist:
dEQP-GLES31.functional.shaders.builtin_constants.tessellation_shader.max_tess_evaluation_texture_image_units
dEQP-GLES31.functional.tessellation_geometry_interaction.feedback.tessellation_output_quads_geometry_output_points
dEQP-GLES31.functional.ubo.random.all_per_block_buffers.25
