      Official build:
       - Build standalone Portable PDBs to reduce the size of the binaries.
       - Convert Portable PDBs to Windows PDBs and publish the converted PDBs to Symbol Store to allow WinDBG, 
         Watson and other tools to find symbol format they understand.

      Jenkins build:
       - Embed PDBs to make it easier to debug Jenkins crash dumps.

      Developer build:
       - Embed PDBs to be consistent with Jenkins builds.
