Add source indexing to package_etw.bat

This change uses https://github.com/Haemoglobin/GitHub-Source-Indexer.git
to source index the UIforETW PDBs so that debugging will automatically
download the correct source file.

This change also creates an etwsymbols.zip file which will be uploaded
with subsequent releases.

+@rem Source indexing as described here:
+@rem http://hamishgraham.net/post/GitHub-Source-Symbol-Indexer.aspx
+@rem The next steps assume that you have cloned https://github.com/Haemoglobin/GitHub-Source-Indexer.git
+@rem into the parent directory of the UIforETW repo.
+@rem You also have to enable execution of power-shell scripts, by running something
+@rem like this from an administrator command prompt:
+@rem powershell Set-ExecutionPolicy Unrestricted
+@rem Note that -dbgToolsPath and -verifyLocalRepo had to be added to the command line
+@rem to get the script to behave. -dbgToolsPath is tricky because the default path has
+@rem spaces and the script can't handle that, so I copy it to %temp%. God help you if
+@rem that has spaces.
+@rem verifyLocalRepo comes with its own challenges since github-sourceindexer.ps1 does
+@rem a weak job of looking for git.exe. I had to edit FindGitExe to tell it exactly where
+@rem to look - something like this:
+@rem function FindGitExe {
+@rem  	$gitexe = "c:\src\chromium\depot_tools\git-2.8.3-64_bin\cmd\git.exe"
+@rem     if (Test-Path $gitexe) {
