cmake: allow client apps to load static plug-ins
Based in part on Kyle Edwards's implementation :
https://codereview.qt-project.org/c/qt/qtbase/+/243731
Example :
```
cmake_minimum_required(VERSION 3.15)
project(foo)
add_executable(foo main.cpp)
find_package(ICU COMPONENTS i18n uc data REQUIRED)
find_package(Qt6 COMPONENTS Core Gui REQUIRED)
target_link_libraries(foo Qt6::Core Qt6::Gui)
qt_import_plugins(foo
INCLUDE
Qt6::qxcb
EXCLUDE
Qt6::qgtk3 Qt6::qeglfs-kms-integration Qt6::qjpeg
)
```
