add a filter on WP_User::get_data_by()

[stefanxyz]

Hello i speak about this function ​https://github.com/WordPress/wordpress-develop/blob/6.3/src/wp-includes/class-wp-user.php#L193-L260

function WP_User::get_data_by()

$user = $wpdb->get_row(

$wpdb->prepare(

"SELECT * FROM $wpdb->users WHERE $db_field = %s LIMIT 1",
$value

)

);

It would be cool to filter the query or provide a own query.

Backstory: i run a shop under different domains and want that user can register with the same mail on different domains but in background is the same WP Instance.
