fix(ruler): show ruler of curwin with no statusline in cmdline

Browse Source 
Problem: After neovim/neovim@846a056, only the ruler for current floating or
last window without a statusline is drawn in the cmdline. This means that if the
current window is not one of these, but has no statusline, its ruler will not be
drawn anymore.

Solution: Make `showmode()` draw the ruler of the current window or the last
window in the cmdline if it has no statusline. This also maintains the
previously restored floating window case (`float->w_status_height` should be 0).

This behaviour should again match Vim, but without the overdraw it seems to do
to achieve the same effect; it calls `showmode()` to draw the ruler for the last
window without a statusline, then may draw over it in `showruler()` (which is
now `show_cursor_info_later()` in Nvim) to show the ruler for the current
window..? It's very confusing.

Also update the logic in `win_redr_ruler()` to mirror the check done in
`showmode()`, so that the ruler doesn't potentially draw over the long
ins-completion mode message in some cases.
