wix: switch Mercurial Windows installer to use py2exe --bundle 3
--bundle 3 leaves all of the compiled C extensions and other DLLs outside of
the library.zip, so we no longer add the installer folder to the system PATH.
Instead, we now ship a small bin/hg.cmd and it is placed in the PATH.
Switching to py2exe --bundle 3 is necessary because the higher bundle options
are not supported on x64.
