CMake: Add non-qtbase configure argument placeholders

The qtbase Coin instructions will start reading the values of the
environment variables NON_QTBASE_CONFIGURE_ARGS and
NON_QTBASE_TARGET_CONFIGURE_ARGS.
These are used to pass configure args to repositories other
than qtbase to allow disabling certain features per-repo.

Unfortunately we have to explicitly set the env var values to empty
strings so that the instructions work correctly, otherwise Coin
replaces them with a '<no value>' token, which breaks the
CMake configuration phase.

For some reason the issue only happens on the Windows MSVC
configuration, but we set them for the other configurations as well
to avoid any future breakages.
