Message:

Improve lazyloading of comment meta in WP_Query loops.

Lazy-loading logic is moved to a method on WP_Query. This makes it possible
for comment feeds to take advantage of metadata lazyloading, in addition to
comments loaded via comments_template().

This new technique parallels the termmeta lazyloading technique introduced in
[34704].

Fixes #34047.
