vim-patch:9.0.1461: ruler not drawn correctly when using 'rulerformat'

Problem:    Ruler not drawn correctly when using 'rulerformat'.
Solution:   Adjust formatting depending on whether the ruler is drawn in the
            statusline or the command line. (Sean Dewar, closes vim/vim#12246)

This issue was made apparent after neovim/neovim@0f1e2b6, as `showmode()` calls
`win_redr_ruler()` with `curwin` now if it's floating, rather than the last
window if there's no statusline (which usually already shares its right side
with that of the editor).
