 Sometimes menu items are best floated, sometimes they're best as inline-
 blocks. Whitespace between the `li`s can have an affect on layout for the
 later.

 Let's allow theme authors to control the white space between menu items:

 * remove `\n`, `\r`, `\t` string replacement in wp_page_menu since [9246]
 * Introduce `item_before` and `item_after` arguments to
   - `wp_nav_menu`
   - `wp_list_pages`
   - `wp_page_menu`
 * `item_before` defaults to an empty string
 * for the first two functions `item_after` defaults to a line-break to
 match the current behaviour
 * for `wp_page_menu`, `item_after` defaults to an empty string to match
 the current behaviour

 Related #27762 and #35107.

 Patch will need to follow the resolution of #35107.
