Subject: [PATCH] Query:

Add a query var, `title`, that allows you to query posts by `post_title`. To accomplish this now, you have to do something like:

{{{
$tacos = get_posts( [
  'post_type' => 'taco',
  's' => $name,
  'exact' => true,
  'sentence' => true,
  'post_status' => 'publish',
  'fields' => 'ids',
  'posts_per_page' => 1
] );
}}}

Adds unit tests.

Fixes #33074.
