shader_jit/tests: Add additional shader-jit tests (#6648)
* shader_jit/tests: Add support for multiple inputs Allows for multiple `Vec4f` inputs for each run * shader_jit/tests: Add additional shader-jit tests Add some more expansive tests for each of the shader-instructions for regression-testing. `MAD`/`MADI` is not added due to an upstream bug in nihstro: https://github.com/neobrain/nihstro/issues/68
