This follows up on 733be4ed7dcf976719f424c0cb81b77a14f91f5a, which made mlir-vulkan-runner and its associated passes redundant, and completes the main goal of #73457. The mlir-vulkan-runner tests become part of the integration test suite, and the Vulkan runner runtime components become part of ExecutionEngine, just as was done when removing other target-specific runners.
