Most qt repos and modules are now ported from qmake to CMake. The
CMake API for internal Qt modules has evolved, and these tools have
not been kept up-to-date. It's time to remove them. Developers can
still use qmake2cmake for their own user projects, which is hosted in
a different repo.
If we do end up needing the scripts again, they can be used from one
of the older branches like 6.9.
