vim-patch:c527d90: runtime(netrw): honor `g:netrw_alt{o,v}` for `:{S,H,V}explore`

Make `:Sexplore` / `:Hexplore` / `:Vexplore` commands honor the user
`&split{right,below}` settings (or netrw-specific `g:netrw_alt{o,v}`)
instead of hardcoding a split direction. Similarly, update banged
variants of the two latter commands to follow the inverted preference.

closes: vim/vim#15417
