Add the functionality to build a framework dependent (shared framework) package for PowerShell.
The changes create two packages, one for Windows and other for Linux, due to #if code.
update the Windows release build script with the ability to capture all the project.assets.json files
add a Windows build to use the new feature in the release build script
update the Linux release build script with the ability to capture all the project.assets.json files
-no new build is needed because signing is not currently automated
The main purpose of this was to enable full symbols for windows release build.
Also makes explicit where we are optimizing and where we are not optimizing due to https://github.com/dotnet/corefx/issues/29700
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.
Fix#6073
The Linux release build was broken because AppImage,tar,tar-arm in build.json is turned into a string of "AppImage,tar,tar-arm" by docker run. Now it's changed to use switch parameters.
Create linux-arm tarball package in our release build.
Also moved the Linux-x64 tarball creation to Ubutntu 14.04, because Start-PSBuild adds additional symbolic link files when running on Red Hat Family distros.
Note that linux-arm can only be built on Ubuntu, so the tar-arm package will also be generated from the Ubuntu 14.04.
