Color console output based on LogLevel

Uses the same approach as .NET's built-in console formatters by writing ANSI escape codes to the TextWriter

I think that some Errors are logged directly too, so they won't always be red with this change

I think it makes sense to maintain consistency with AnsiConsole

It does look like in those case, we are doing things like this?

src\dotnet-scaffolding\dotnet-scaffold\Interactive\Flow\Steps\ParameterDiscovery.cs: AnsiConsole.MarkupLine($"[red]Error with EntraID scaffolding in az cli environment: {azCliError}[/]");?

I do see some cases where we are doing direct Console.WriteLines though - maybe those should be routed through LogError
