Adds a new mlir-opt test-only pass, -test-spirv-cpu-runner-pipeline, which runs the set of MLIR passes needed for the mlir-spirv-cpu-runner, and removes them from the runner. The tests are changed to invoke mlir-opt with this flag before running the runner. The eventual goal is to move all host/device code generation steps out of the runner, like with some of the other runners. Recommit of17e9752267. It was reverted due to a build failure, but the build failure had in fact already been fixed ine7302319b5.
