Sergey Biryukov 2c06c9afd5 Query: Check if $wp_query is set in query loop functions. ...

This avoids a PHP fatal error if any of these functions are called too early:

* `have_posts()`
* `in_the_loop()`
* `rewind_posts()`
* `the_post()`
* `have_comments()`
* `the_comment()`

bringing some consistency with conditional tags: `is_single()`, `is_home()`, etc.

This commit also removes unnecessary `return` from `the_comment()`, for consistency with `the_post()`. As `WP_Query::the_comment()` does not have a return value, this statement did not have any effect in practice.

Follow-up to [4934], [8807], [16947], [17068], [17083], [49147], [53395], [53396], [53400].

Fixes #55722.
