pyoxidizer: pass arch to WiXInstaller() We just upgraded Windows automation to PyOxidizer 0.17.0. This version of PyOxidizer changed the behavior of WiX installers so installer architecture defaulted to "x64" (before it defaulted to the target of the pyoxidizer.exe binary). To allow controlling the architecture of the installer, the `arch` argument was added to `WiXInstaller`. This commit passes that argument in.

contrib: install PyOxidizer 0.17.0 This pulls in some changes we want to improve Windows MSI installers. This will need separate enhancements to the pyoxidizer.bzl. But those will be handled in a separate changeset. Differential Revision: https://phab.mercurial-scm.org/D11357

packaging: reference proper output directory 9438e9b7321a changed the name of the PyOxidizer target, which changed the name of the output directory. The code changed by this patch wasn't properly updated by that changeset. This resulted in a run-time failure due to trying to read from a non-existent directory. This change should fix the building of Python 3 Inno installers. Differential Revision: https://phab.mercurial-scm.org/D11356

packaging: pass extra_pyoxidizer_vars only to pyoxidizer Before, we would attempt to call a function (build_installer_py2exe) that didn't accept this keyword argument. This was preventing the building of py2exe installers. Differential Revision: https://phab.mercurial-scm.org/D11355
