This is a breaking change for the delegate types with the object return type:
Before this change, the returned object will always be an PSObject instance.
After this change, the returned object is the underlying object, which could still be an PSObject if that's what the script actually returns.
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
Manually reviewed each change.
