e_client: added support for 'wm.policy.win.rot.render.nopending' aux hint.

The display server doesn't block application rendering if the client window
has a 'wm.policy.win.rot.render.nopending' aux hint during rotation.

Each module can check wheter this aux hint is set by using
ec->e.state.rot.nopending_render member.
