Remove the legacy implementation of emulation for OoO queues. This code predated the PI and UR layers in DPC++ because fpga OpenCL did not support OoO queues. Today, this type of thing should be done by the backend compiler or UR layer.

Note that I was seeing an issue in a Graph unit test. Graph recording was doing strange things. I added # if 1 / #endif around the test to easily toggle things on/off for now. If the actual commands during recording are omitted, it was fine.

I will create an internal ticket to look into the graph issue.

The test fails were random test timeouts that seem unrelated to these changes.

Turns out I also nuked 1 if statement too many. That resolves the Graph issue I was seeing.
