 Don't use `array_merge()` when building comment children arrays.

 `array_merge()` is much slower than building the combined array using a
 `foreach` loop. The performance difference was causing a speed regression
 with
 the `get_children()` functionality introduced in 4.4.

 Merges [35931] to the 4.4 branch.

 Props rogerhub.
 Fixes #35025.
