Update the operator documentation generation (#7787)

* Update the operator documentation generation
  - Make layout a little nicer
  - Update to latest supported operators including training
  - Fix some links that are broken when the docs content is copied to github-pages
  - Fix incorrect usage of 'onnx.ai.ml' as the default domain
    - ML ops are now separated from the real default domain of 'onnx.ai'
  - Include CPU, CUDA and training kernels
    - exclude DNNL as it's not an EP we own

* There are separate paths for CUDA and CUDNN as they are not guaranteed to be in the same location on a Windows machine. Use the CUDNN path when looking for the CUDNN library.

* Enable validation of both contrib ops and operator kernels in build
Filter generation so it's deterministic
Add ability for CI to publish the md files as build artifacts if they differ so a developer can download and add to their PR to resolve any diffs.
Remove workarounds for github-pages as that will now link to the github docs which display correctly
