[Feature] New delegate for OnCommissioningWindowClosed after commissioning timeout expired

[mishadesh]

Feature description

Matter SDK has the feature, when the Commissioning window closes after some time of inactivity (15 minutes).
In this case the void OnCommissioningWindowClosed() called. But this function is also called if the Commissioning process closed the BLE session.
There is no mechanism to determine, on which reason the Commissioning window was closed.

In this pull request we can see that the call OnCommissioningWindowClosed() is adding misunderstanding at which situation was it called and forces us to make a special handling of the reason, why the window was closed. This delegate doesn't have any arguments, so we need to determine, was the session opened previously or not.

My proposal, that we need to add the argument to the delegates and forward the reason of calling this delegate.
Or we need to create a new delegate to handle the specific cases of closing the commissioning window.

Please read the conversation in the pull request to get familiar with the issue.
