feat(helix-view): view debug output on windows

[axdank]

Tmux is not available on windows, so it raises an error and closes the helix editor with a warning pointing to handlers/dap.

Therefore I decided to add a piece of code so that a new terminal can be opened, either with Windows Terminal or Conhost ( both running cmd.exe inside ).

In case of having windows terminal ( wt.exe ), it is executed in it.

In case of not having it, it is executed in ( conhost.exe ).

Example ( conhost.exe ):

Example ( wt.exe ):

@the-mikedavis Sorry, I wanted to check if this code can be applied. Previously I created a pull request (of the same thing) but I didn't realize that the code was formatted and generated unnecessary changes in git (+331, −311 ), so I closed it and recreated it correctly.

This looks good to me but let's wait for a maintainer with more rust experience to review 👍

The idea is to have this configurable via an editor.terminal = { cmd = "foo", args = ["bar"] } type setting with some reasonable defaults similar to how the clipboard works. Would you be prepared to work on that in this PR? If not I can merge this as is for now and open a separate tracking issue

@archseer If there is a possibility to merge this momentarily, it would be the best, because my knowledge in rust is still very basic 😞.
