refactor(tvix/eval): rename Opcode::DataLocalIdx to DataStackIdx

Browse source 
It is very confusing that this opcode is called DataLocalIdx, but it
carries a StackIdx rather than a LocalIdx.  It seems like this
really ought to be called DataStackIdx, but maybe I've
misunderstood; if so please explain it to me.
