Niels Lohmann c09fa3047d Make the index text of items() on arrays lazy

basic_json_view::items() on an array formatted every element's index with
std::to_string when the item was made, whether or not the loop asks for the
key. The item now keeps the position and makes the text on the first key()
call. Objects are not affected.

Iterating over the items of an array of 3000 numbers and reading only the values:
  Apple M1: 25.5 us -> 4.6 us (0.45 M -> ~0 net instructions)
  Linux x86-64 Ir (whole run), GCC 13 / Clang 18: 14.9 M -> 4.1 M / 15.3 M -> 4.6 M
Reading key() costs what it did (24.5 us).

Belongs to the PR "json_view: read-side speedups".
