Default to DefaultConsoleWidth when DotNet says WindowWidth is 0
This resolves an issue in an environment like VSTS when pwsh is spawned and DotNet is not able to determine the Console Width.
* Port changes from #6883 by @kalgiz
Use safe pattern 'columns <= columnsThresHold ? stackalloc int[columns] : new int[columns];'
Remove duplicate code.
Use common 'columnsThresHold' constant.
* Add checking if an output width is specified.
* change _failedToReadConsoleWidth variable to _noConsole bool value.
This variable is to cache the default console width when failed to get 'Console.WindowWidth' value.
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
