 Background: #52995.

 Some properties of the `WP_Post`, `WP_Term`, and `WP_User` classes are
 documented as integers, so it should be a safe assumption to always treat
 them as such. However, that is not the case when `get_post()` or
 `get_term()` is called with an `edit`, `attribute`, or `js` context,
 because all values are run through `esc_attr()` or `esc_js()` in that
 case, and these properties are unexpectedly converted to strings.

 As WordPress moves to strict type comparisons in tickets like #52627 or
 #52482, it is important to make the type of these properties consistent in
 all contexts, so that using strict comparison does not cause unexpected
 issues.

 This applies to the following functions:

 * `sanitize_post_field()`
 * `sanitize_term_field()`
 * `sanitize_user_field()`

 and the following properties:

 * `WP_Post::ID`
 * `WP_Post::post_parent`
 * `WP_Post::menu_order`
 * `WP_Term::parent`
 * `WP_Term::term_id`
 * `WP_Term::count`
 * `WP_Term::term_group`
 * `WP_Term::term_taxonomy_id`
 * `WP_Term::object_id`
 * `WP_User::ID`
