st,ir3,radeonsi: push lower_deref_instrs back into driver

vc4+vc5 is not really effected by the deref chain to deref instr
conversion, so it no longer needs this pass.  For others, now that
all the passes mesa/st uses are using deref instructions, push the
lowering to deref chains back into driver.
