The archiver tool from the MSVC toolset is lib.exe. It has different
parameters then it's GNU counterpart "ar".
buildtools\meson.build was updated to use lib.exe when MSVC compiler is
used. This is to allow the code to be built without requiring GNU "ar"
to be installed in that scenario.
Script gen-pmdinfo-cfile.py was updated to use the correct parameters
when using lib.exe.
