Subject: [PATCH] Build Layout PerfView Command (#2099)

Add the ability to build a fully extracted and self-contained PerfView
layout.  This is designed to avoid using the user-specific %appdata%
installation of PerfView for scenarios where systems need to control
updates and deployment of PerfView.
