Alexandru Croitor 21bffeec90 CMake: Add deployment auto test 
Add a cmake test that builds a simple widgets application, installs
it, in a shared Qt build deploys the runtime dependencies and then
runs it to confirm that the app works.
With a static Qt, the installation of the runtime dependencies is
skipped, but the app should still run.

The test is expected to pass only when targeting Windows and macOS
(both when using shared and static Qt).

Pick-to: 6.3
Task-number: QTBUG-98545

# 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
