CMake: Support cross-compilation with qmake
When cross-compiling, we now create a target_qt.conf file that's to be
used with the host Qt's qmake. With "qmake -qtconf .../target_qt.conf"
projects can be cross-built against the cross-built Qt.
We also create wrapper scripts for the host qmake to save the user from
passing the -qtconf argument.
Fixes: QTBUG-82581
