[nrfconnect] Fixed window covering bug in updating cluster attributes (project-chip#18752)

* [nrfconnect] Fixed window covering bug in updating cluster attributes

Nrfconnect window covering example doesn't update window covering
cluster attributes properly.

* Moved PostAttributeChange method from window-covering-server.cpp
to header.
* Called PostAttributeChange method in nrfconnect implementation
of MatterWindowCoveringClusterServerAttributeChangedCallback
* Changed mode default value from 0x14 to 0.

* [nrfconnect] window-app: do not block in chip attribute changed callback.
