freedreno/ir3: move ring_wfi() further up call chain

Hoist them out of code-paths that will eventually be called directly for
various a6xx+ const related stateobjs.

This ends up duplicating one constlen check in ir3_emit_vs_consts(), to
avoid what could otherwise be an unnecessary WFI on older gens.
