add_settings_field: remove duplicated tags

[IanDelMar]

For add_settings_field(), the following types are the same as those documented in core:

'id'       => 'string',
'title'    => 'string',
'callback' => 'callable',
'page'     => 'string',
'section'  => 'string',

Follow-up to #485.y

Also removes some void types that are added via the void analyzer (no effect on the stubs file).
