Complete migration from shark_turbine to iree/turbine namespace

[ScottTodd]

• https://github.com/iree-org/iree-turbine/tree/main/shark_turbine remove (set up forwarding?)
• https://github.com/iree-org/iree-turbine/tree/main/iree/turbine move files here
• https://github.com/iree-org/iree-turbine/blob/main/setup.py update strings in here
• migrate in-tree and out-of-tree samples/tests/etc. to use the new namespace

We've had plenty of time to migrate gracefully, but this is going to be a hard blocker for various packaging workflows very soon, so we might need to do a more abrupt cut over instead.

For example:

• The package name is still set to shark_turbine:

  iree-turbine/setup.py

  Lines 18 to 19 in e0a8fdf

  	# Transitional as we migrate from shark-turbine -> iree-turbine.
  	TURBINE_PACKAGE_NAME = os.getenv("TURBINE_PACKAGE_NAME", "shark-turbine")

  • https://pypi.org/project/shark-turbine/
  • https://pypi.org/project/iree-turbine/

• Documentation and samples across other repositories still use import shark_turbine: https://iree.dev/guides/ml-frameworks/pytorch/

Let's do the rename and beef up a couple of tests to ensure that the old namespace still works while we propagate.

Nice, I see a few commits landed across various repositories. How much is still left to do here, @Hardcode84 ?

• https://iree.dev/guides/ml-frameworks/pytorch/#ahead-of-time-aot-export code samples still use import shark_turbine.aot as aot
• https://github.com/iree-org/iree/tree/main/samples/colab sample Colab notebooks also use shark_turbine still
• https://github.com/iree-org/iree-turbine/blob/main/shark_turbine/__init__.py has a temporary redirect in place. Is that working?

Oh and https://github.com/iree-org/iree-turbine/actions/workflows/test_shark.yml has been failing. That's using this workflow file: https://github.com/iree-org/iree-turbine/blob/main/.github/workflows/test_shark.yml. That clones https://github.com/nod-ai/SHARK-Studio and installs from https://github.com/nod-ai/SHARK-Studio/blob/ec75e08a2dc28684649cba639a9a4ea7cb17013e/requirements.txt#L10 (shark-turbine @ git+https://github.com/iree-org/iree-turbine.git@main)
