Fix for #7268: AppImage won't start

Add support for custom installer steps

Add QGC_DISABLE_INSTALLER_SETUP to CONFIG will override config in QGCInstaller.pri.
However, QGCInstaller.pri can be imported in the custom one. In this way
a custom build can generate it's own installer config or add pre and post steps.

Add support for AppImage customization

Also copy all dependencies of ICU libs to cover all configurations

Exclude ArduPilot code when not used
