Subject: [PATCH] Deprecated support for Windows OS

As was discussed in Neutron team meeting [1], we are going to deprecated
support for running Neutron on Windows OS in 2023.2 cycle and remove it
in 2024.2.
This decision was made due to the fact that the only company who was
behind Winstackers project and was maintaining this Windows support in
Neutron is no longer interested in maintaining it [2].

Closes-Bug: #2015844
