Subject: [PATCH] Return floating_preview window id (#4828)

Make ale#floating_preview#Show more similar to popup_create and return
the id of the window so it's easy to set the filetype of the resulting
buffer.

Update test stub version of Show() to return a win id (the current window
since it's not actually creating a window).

Test
* both tests still pass
