When using the windows installer in French language, the `Hôte` label
used to configure postgresql server does not display correctly.

The LangString documentation does not specify how to use the special
characters but after some tests, specifying a BOM for the nsi file seems
to be the way to go.

Up to Odoo 13.0, the windows setup is 32 bits and embeds an old
postgresql 9.5 32 bits version too.

With this commit, the postgresql server is no longer embedded in the
resulting setup file. Instead, if the user choose to install the
postgresql server, the 12.4 version is downloaded from the official site
(version 10.14 in the case of a 32 bits windows).

Also, the Python target achitecture is choosen based on the Windows
system on which Odoo is installed.

This imply changes on the KVM images used to build the installer:

    - The Windows system on the KVM as to be 64 bits.
    - A 32 bits WinPython version must be in `c:/odoobuild/WinPy32`
    - A 64 bits WinPyhton version must be in `c:/odoobuild/WinPy64`

A little bit of cleaning also comes with this commit to get rid of the
old `openerp` references.

When building the MS Windows package, the PYTHON_VERSION variable is not
used and the WinPython path is hard coded in the Makefile and NSI file.
This prevent the usage of a newer version of Python.

With this commit, the PYTHON_VERSION is used to compute the WinPython
Python directory. That way, this directory can be derived from
package.py command line argument --vm-winxp-python-version.

Also the less windows binaries are not packaged anymore.

Packaging oversight, the displayed version in the installer window was still
12.0.

Fixes #27420

closes odoo/odoo#27590

Nsis installer was installing the wrong MS Visual C++ redistributable
file. Python 3.6 needs MS Visual C++ 2015 redistruibutable files.

Also, Nsis now differentiate Windows architecture for the nssm service
and the MS C++ redist.

Purpose: When uninstalling using the windows uninstaller, python and
nssm were left beyond. This fix removes the python and nssm dirs also.

Purpose: for multiple reasons (bytecode change in python 3.6,
         missing files for some packages, py2exe is unmaintained
         ...) the py2exe solution cannot be used anymore.
         Odoo for windows will now use a portable Python that
         will be shipped with the Windows installer.
         For that purpose, a Winpython 3.6.2 is used.
         In order to build the Windows installer, a Winpython dir
         with all the Odoo requirements fullfilled, must exists on
         the build system (qemu-kvm VM).

* nsis installer:
    - Only the python dir is used to avoid packaging too much stuffs
    - better compression level
    - starts the Odoo service using nssm
    -  bump to V11
* change the default win10 build vm path
* print a warning when uncomplete addon move
* try to force remove of addon path:
  when the addons are moved to Odoo/addons, it happens that the
  destination already exists. In that case, the source addon was not
  deleted, resulting in a uneeded file duplication.
* fix version string to avoid invalid chars in windows service
* Add requirements adpated for WinPython
* package.py now shows the traceback when a build fails
* verify that a file exists before publishing
* debuild now creates an .xz file instead of .gz
* package: use logging module
* kvm CPU that works with older versions.
* fix a pexpect encoding bug
* fix the version to remove special chars '~' which is not appreciated
  by windows services

[REM] win32setup: Remove win32 python service

Purpose:
    Before this commit, the win32 service was managed by an executable
    builded from those two files with the help of py2xe.
    The win32 service is now managed by nssm which starts Odoo and therefore, those
    files are not needed anymore.

no fallbacks were implemented to `openerp-server.conf`.
