build!: remove neovim qt

Neovim QT was originally bundled on Windows as a response to the then
lackluster terminal options. The situation has dramatically changed,
with viable options such as Windows terminal, Alacritty and Wezterm to
name a few. The Windows build no longer needs this special treatment for
neovim to be usable.

Pros:
  - Release builds will be smaller.
  - Less maintenance burden.
  - Clearer separation of responsibility (neovim issues go to the neovim
    repo and neovim-qt issues to the neovim-qt repo).
  - More consistent treatment between platforms.

Cons:
  - Users who've come to expect neovim-qt to be bundled with nvim will
    need to adjust and download neovim-qt from
    https://github.com/equalsraf/neovim-qt instead.
  - Similarly, build scripts will need to be adjusted to reflect this
    change.

Closes https://github.com/neovim/neovim/issues/21209.
