Allow customization of all floating window borders (#4215)

Browse Source 
* Allow customization of all floating window borders

Users may not necessarily want the same border character for top+bottom
or left+right, so allow all eight border characters to be configured in
g:ale_floating_window_border.

For backwards compatibility, the old rules are still applied if only six
elements are given.

* Reorder popup border array for compatibility
