ivigenerator: Fix the qmake integration on windows

We need to depend on debug_and_release for windows
and return an error if it has been disabled.

This is needed as NMAKE doesn't support the Makefile
target and it's own reevaluation, which is needed
for the normal qmake integration to work.

The workaround is based on the fact that sub Makefiles
are generated and we can run the generator and
qmake before NMAKE is reading them.
