runtime: refine the last_event in queue to a list
Refine the event struct to make last_event become a list to store
all uncompeleted events and update them every queue flush. This can
make sure all events created in the runtime have a chance to update
status and run callback functions and then be deleted. We will also
fix the memory leak problem casued by uncompeted events.
This is a bugfix for https://bugs.freedesktop.org/show_bug.cgi?id=91710
The leaked events with gpu buffers will be unreferenced and cause other
drm buffer leak and result in terrible memory leak.
