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.

Interactive hosts expect an `IncompleteParseException` to signal that more input is expected.
When detecting errors, the parser can report 2 positions:
* where the error should be reported
* where the error was detected
Typically these are the same, so most error reporting methods have a single parameter.
For missing braces, the pattern is supposed to be to report the error after the opening brace, but the error is typically detected at the end of the file.
There were a few places where we were not consistent in reporting such errors, this PR corrects those places.
