Add blender launcher application when building with MSVC

Main idea of this change is to make a small executable which
will set OMP_WAIT_POLICY environment variable and then will
launch blender itself.

This is a teporary solution for the time being we'll have a
more clear solution to high CPU usage with OpenMP when building
with MSVC.
