97358730 - [mlir][mlir-vulkan-runner] Move part of device pass pipeline to mlir-opt (#119372)

[mlir][mlir-vulkan-runner] Move part of device pass pipeline to mlir-opt (#119372) Adds a new mlir-opt test-only pass, -test-vulkan-runner-pipeline, which runs a set of passes needed for mlir-vulkan-runner, and removes them from the runner. The tests are changed to invoke mlir-opt with this flag before invoking the runner. The passes moved are ones concerned with lowering of the device code prior to serialization to SPIR-V. This is an incremental step towards moving the entire pipeline to mlir-opt, to align with other runners (see #73457).
