Add mechanism to preallocate cmd buffer allocations in command stream
receiver reusable allocations list per command queue initialized.
This should limit additional allocations during hot loop.
Needs to be enabled in subsequent commits by setting product helper
method.

In L0 its not possible to track objects relations. For example CmdList
may be removed before Event.
In such case, Event needs to safely skip unregister call, without
accessing CmdList/CmdQueue object.

Program barrier to task stream, before next enqueue kernel.
This will reduce the number of batch buffer starts for sequences of
enqueue, barrier, enqueue, ... .

Use flushStamp=taskCount when passed flushStamp==0.
This will cause driver to busy wait for a short while before falling
back to use kmd notify.

- 3D btd command should be programed only once per context
- Add conditional pipe control command prior dispatching 3D btd command
- share 3D btd state between immediate and regular command lists
- add pipe control after ray tracing kernel to invalidate state cache

When state base address tracking is enabled and command list use private heaps
then command list at destroy time must calls all compute CSRs that were using
that heap to invalidate state caches.
This allows new command list to reuse the same heap allocation for different
surface states, so before new use cached states are invalidated.

- full properties update is time intesive task and must be done only once
- selective update can be done after initial update
- dirty flag will allow to distinguish initial update is done
