client: Notify application code of button release after leave

Browse Source 
There is a code path to notify application code that mouse buttons are
released following a drag.

Compositors we will have been sent a leave event in the
meantime, making this code inert. Focus window will be null, and
mButtons will be empty.

We still need to send a release event QWindowSystem event to no window,
as we need to update any grabs on the device.

Pick-to: 6.8
