Subject: [PATCH]     Add option to not reverse select_next_item on bottom_up
 list (#1346)

    * add feature requested in (#1346)

Add a parameter to the function preserve_mapping_verticality, which will keep mappings like <Up> and <Down> not reversed even when used custom view is used with `selection_order = 'top_down'` configuration.

Example use configuration:
```
    ["<Down>"] = cmp.mapping(cmp.mapping.select_next_item { behavior = cmp.SelectBehavior.Select, preserve_mapping_verticality = true }, { "i", "s" }),
    ["<Up>"] = cmp.mapping(cmp.mapping.select_prev_item { behavior = cmp.SelectBehavior.Select, preserve_mapping_verticality = true }, { "i", "s" }),
```
