Subject: [PATCH] [CI] Migrate intel.github.io/llvm-docs/ to `intel/llvm`
 (#15483)

Follow up of https://github.com/intel/llvm/pull/15482

This PR enables hosting [intel.github.io/llvm-docs/
](intel.github.io/llvm-docs/) website from intel/llvm. Generated docs
will be uploaded as an artifact and will be used to host GH page
(https://docs.github.com/en/pages/getting-started-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site#publishing-with-a-custom-github-actions-workflow).

The new URL of the website will be **intel.github.io/llvm/**
Example: https://uditagarwal97.github.io/llvm/
