Improve Unix Console.ReadLine by borrowing from PowerShell's ReadLineFromConsole

[tmds]

On Unix, .NET uses its own Console.ReadLine implementation which is very minimalistic.

PowerShell has a more feature rich ReadLine implementation here: https://github.com/PowerShell/PowerShell/blame/5cd04f2377b624dedd17a85ff3f38a0343292477/src/Microsoft.PowerShell.ConsoleHost/host/msh/ConsoleHostUserInterface.cs#L1567.
It include things like: arrows keys, home, end, delete, ...

We can borrow some things from that to improve the UX of Console.ReadLine on Unix.

We would get #38051 fixed? That would be great! I am supportive of that idea.

[tmds]

Yes, arrow keys are part of this.

You can assign this to me.

Closing in favor of #38051. See comment: #38051 (comment).
