[hipDNN] Adding hipDNN python packaging

[mousdahl-amd]

Motivation

Add hipDNN & MIOpen plugin to the python wheel packaging.
The purpose of this change is to enable hipDNN integration with Pytorch.

This PR supercedes #2958

Technical Details

• Added hipDNN + plugin project to the packaging script.
• Added hipdnn to _dist_info.py matching with other libraries
• Updated documentation to include details of hipDNN
• Updated build_python_packages.py to allow generic targets to be installed alongside device targets
  • For now this enables hipDNN to be installed alongside other library components.
  • Note: Once RFC0008 is implemented then hipDNN & the plugin should be moved to the host only locations along side the other library projects.

Test Plan

Run a test of the Release portable Linux packages workflow & Windows packages workflow:

Linux test wheels (run here unrelated jax break):

pip install \
  https://therock-dev-python.s3.amazonaws.com/v2/gfx94X-dcgpu/rocm-7.12.0.dev0%2Be7125827ee12837fefbd91de4b3d1a8b9f0b2425.tar.gz \

  https://therock-dev-python.s3.amazonaws.com/v2/gfx94X-dcgpu/rocm_sdk_libraries_gfx94x_dcgpu-7.12.0.dev0%2Be7125827ee12837fefbd91de4b3d1a8b9f0b2425-py3-none-linux_x86_64.whl \
  https://therock-dev-python.s3.amazonaws.com/v2/gfx94X-dcgpu/rocm_sdk_devel-7.12.0.dev0%2Be7125827ee12837fefbd91de4b3d1a8b9f0b2425-py3-none-linux_x86_64.whl

Windows test wheels (run here):

pip install ^

Test Result

Wheel builds are successful with the hipDNN artifacts included.
Additional artifacts from hipDNN are present, and installed correctly.

Please update the PR title to a good commit message (i.e. not starting with the branch name like "Users/[username]")

[mousdahl-amd]

I'm going to switch this to draft until we can get our frontend flatbuffer dependency sorted out.

[mousdahl-amd]

Alright @ScottTodd , I think we're ready now!

[ScottTodd]

Can you resolve the conflicts and then re-request review? I might need to find another reviewer for this too, I can't spare much time lately.

[mousdahl-amd]

We had a green signal before resolving a small conflict with main: https://github.com/ROCm/TheRock/actions/runs/22327111496?pr=3461

lgtm overall, looks like python does build and tests pass for both linux + windows
