In WP_Comment_Query, parse meta_query vars after the pre_get_comments hook.

Browse Source 
[31467] included a change that involved generating meta_query SQL before the
`pre_get_comments` hook, with the result that `pre_get_comments` callbacks were
no longer able to modify comment meta queries. We fix the problem by moving the
SQL generation to after the hook.

This changeset also includes a second call to `meta_query->parse_query_vars()`,
to ensure that modifications to metadata-related query vars (such as `meta_key`
and `meta_value`) performed in `pre_get_comments` callbacks have the expected
effect on the comment query.

Fixes #32762.
