Alexey Edelev 9bd418aeab Implement generating of a module cpp export header 
Add an option that automatically generates an export header for a Qt
module. The header contains only Q_DECL_EXPORT/Q_DECL_IMPORT related
content, so it's not a full replacement of 'global' header files.

Task-number: QTBUG-90492
Change-Id: I250d1201b11d4096b7e78e61cbf4565945fe6517

# This is an automatic test for the CMake configuration files.
# To run it manually,
# 1) mkdir build # Create a build directory
# 2) cd build
# 3) # Run cmake on this directory
# `$qt_prefix/bin/qt-cmake ..` or `cmake -DCMAKE_PREFIX_PATH=/path/to/qt ..`
# 4) ctest # Run ctest
# 5) ctest -V -R test_wrap_cpp_options # Run single test
