perf(ivy): avoid generating selectors array for directives without a selector (#33431)

Now that we've replaced `ngBaseDef` with an abstract directive definition, there are a lot more cases where we generate a directive definition without a selector. These changes make it so that we don't generate the `selectors` array if it's going to be empty. PR Close #33431
