Minor cleanup around read/subscribe(To)AttributePaths. #26171

  1. Use initWithArray:copyItems:YES when copying arrays, instead of hand-rolling
    the copy.
  2. For read, empty paths should just lead to an empty result, not an error, just
    like they would if the read actually happened.

Fixes #26169
