[Chromoting] Build Chromoting Host installation in two steps: (binaries & .wxs) -> .zip -> .msi.

The two step process is needed so that we could take the produced .zip and use it to sign the binaries and installation on a separate machine. Decompiling .msi using dark proved to be a bad idea due to bugs in dark.exe.

The previous attempt to land this CL failed due to tour custom actions and
msbuild using the same folder. The 1st patch is the original CL. The 2nd one is
a fix for msbuild issues. PTAL.

Step "update" is always a major failure.
Look at the try server FAQ for more details.
