Alexandru Croitor d0c2425d79 CMake: Choose better defaults for qt_add_plugin STATIC/SHARED
There was a recent behavior change where the public CMake API
qt_add_plugin API took into account the value of BUILD_SHARED_LIBS
to decide whether the plugin should be a static or shared library.

Instead, use the following new behavior

 - If no explicit option STATIC / SHARED option is passed, default to
   whatever flavor Qt was built as.
   Aka if Qt was configured with -shared, qt_add_plugin defaults
   to creating shared plugins. If it's a -static Qt, create static
   plugins.
 - If an explicit STATIC / SHARED option is set, override the default
   computed value with the given value.

As a result BUILD_SHARED_LIBS does not affect Qt plugins anymore. This
is more in line with Qt expectations.

Add SHARED as a new valid option to pass to qt_add_plugin (it wasn't
before).

Add tests to check for the above behavior.
