feat(term): enable reflow by default (#21124)

Browse Source 
libvterm v0.3 supports reflow of terminal buffer when Nvim is resized
Since v0.3 is now a required dependency, enable it by default to find
(and fix) possible issues.

Note: Neovim's scrollback buffer does not support reflow (yet), so lines
vanishing into the buffer due to a too small window will be restored
without reflow.
