This PR introduces a new MLIR converter and water emitter that translates Wave kernel traces into MLIR code using the Wave dialect.
It adds:
mlir_converter.py: Serializes Wave kernel execution traces and spawns the water emitter process
water_emitter.py: Standalone process that generates MLIR wave dialect ops using Water Python bindings (incompatible with IREE bindings)
lit_tests/mlir_converter.py: Verifies the converter works correctly with a simple matrix addition kernel
