Host needs updating for $psStyle

[jhoneill]

I filed an issue on the mail PowerShell project PowerShell/PowerShell#16643
Basically hosts other than "ConsoleHost" - including the Visual Studio Code Host need to be updated so that when $PSStyle.OutputRendering is set to plaintext Ansi colours are not sent to the terminal

Above you can see the green row labels in the PowerShell Integrated Console. Below you can see they're mono in the PWSH console.

What I'm being told over there is that fix goes with the host. hence creating this one.

Thanks for the bug report @jhoneill! We have a lot of work to do for the integrated console's host, especially with respect to the new PSStyle APIs.

There's a discussion going on about whether this should be in host, and if it reasonable to drop this work onto you.

FWIW the latest preview seems to work in both Host and Ansi mode, except for exceptions:

Detailmode kind of works but clearly has issues:

Sweet, looks like things are improving! Patrick had the idea of redirecting the host's PrivateData field to the underlying console host, and not that I know much about this but it seems to have made more host things work?
