Subject: [PATCH] build: request Qt CorePrivate/WidgetsPrivate components in
 application-tray

application-tray links against Qt6::CorePrivate and Qt6::WidgetsPrivate but
only requests the public Core, Gui, Widgets and DBus components. From Qt
6.10 those *Private imported targets are no longer available transitively,
so configuring fails unless the private components are requested explicitly:

  CMake Error at plugins/application-tray/CMakeLists.txt:70 (target_link_libraries):
    Target "application-tray" links to: Qt6::CorePrivate
    but the target was not found.

Gate the private find_package on Qt >= 6.10, matching the pattern used in
dtklog and other Deepin projects, while still requesting both CorePrivate
and WidgetsPrivate because this target links both.

Reproduced on a pristine checkout with Qt 6.11.1.
