Add pdb-path parsing to GetDebugID

This CL is adding the field pdb-path to the GetDebugID signature.

  1) Make optional GetDebugID fields (they can be null)
  2) Add a pdb-file parameter
  3) Add the pdb-path to chrome-trace (vmmaps dumps)

Each PDB has a unique DebugID and a PDB-Path used to retrieve the debug
information. The crash servers required both field to fetch the breakpad
debug file.
