accel/ivpu: Send VPU_JSM_MSG_CONTEXT_DELETE when deleting context

The VPU_JSM_MSG_CONTEXT_DELETE will remove any resources associated
with the SSID, that included any blobs create by the user space
application.

The command can also remove doorbell registrations, but since this
does not work in HW scheduling case, we do not depend on this
capability and unregister the doorbells explicitly.
