PDB (debuginfo) files can be quite large, do we want to install them?

As you may have seen, build fails because find_program() result cannot be
used in meson.add_install_script() until 0.55. Since your script has
Unix-specific part anyway and Windows recommends Meson 0.56, maybe Unices
should continue using shell variant and Python script can be Windows-only.
