Add gpu build

[laserprec]

Description

To improve developer experience working with this repo, we will begin migrating our DevOps pipelines into Github Action, along with consolidating documentations and leveraging popular DevOps tools like tox and flake8. This will be a sequence of updates to our DevOps infrastructures:

1. Propose and draft the CI pipeline in Github Action
2. Setup self-hosted machines to run our GPU workloads <---- (Current PR)
3. Run tests on the appropriate dependency subsets
4. Create feature parity with the existing CI pipelines (pr-gates & nightly-build)
5. Optimize build time for unit tests
6. Enforce flake8 (coding style checks) on the build and clean up coding styles to pass flake8 checks
7. Deprecate CI pipelines in ADO and switch to Github Actions

In THIS PR

we have the following changes:

• Add a GPU build step to PR-gate
