-This is required to enable N:1 submission model.
-If heaps are coming from different command queues that always
mean that STATE_BASE_ADDRESS needs to be reloaded
-In order to not emit any non pipelined state in CSR, this change
moves the ownership of IndirectHeap to one centralized place which is
CommandStreamReceiver
-This way when there are submissions from multiple command queues then
they reuse the same heaps, therefore preventing SBA reload
