CMake: Introduce QT_DEBUG_FIND_PACKAGE for troubleshooting
When a Qt component or dependency is not found, we will now show a
message that the user can reconfigure the project with
-DQT_DEBUG_FIND_PACKAGE=ON.
If the option is enabled, various variables that find_package uses to
find packages (like CMAKE_PREFIX_PATH, CMAKE_FIND_ROOT_PATH) will be
recorded before each find_package / find_dependency call that is
executed in any of the Qt package files.
If any find_package call fails (a package has its _FOUND variable set
to 0), the values of all those recorded variables will be shown.
This is useful to troubleshoot issues, especially when
cross-compiling, without having to manually modify the various
Config files.
