Hide debug console when using "console": "integratedTerminal" (#6523)

Previously the C# extension would always set `internalConsoleOptions` (which controls if VS Code shows the debug console) to `openOnSessionStart`. The PR changes things so that we will use `neverOpen` if we are going to use the integrated terminal.

This resolves #6516
