Refactor CI/CD implementation

[greole]

This PR consolidates our github workflows.

• It puts all static checks like spdx header check, formating, spell check into a single workflows as multiple jobs.
• It adds an IWYU check to the buid based clang-tidy workflow. Currently, we don't enforce IWYU compliance.
• Add an aws workflow to build with cuda and execute tests.

@HendriceH I added the compile_on_aws.yaml workflow, but the workflow doesn't show up yet. Maybe the NeoFOAM repo needs do be enabled?

Hi @greole, I think the workflow yaml file needs to be present in main, otherwise it won't show up. Other ideas would be the file ending: Does it need to be .yaml or .yml? Or does it need to be in a subdirectory "workflows"?

The file name should be correct, I copied it from the ogl folder. Do we need to create some credentials/tokens? I think we did that for the hpsim repositories but not the exasim-project yet?

Yes you need to create a token (with repository scope) and add it to the repository secrets -> actions under the name: GH_PERSONAL_ACCESS_TOKEN

Ok I can start the job on aws now but it fails with: Error: Could not assume role with OIDC: Not authorized to perform sts:AssumeRoleWithWebIdentity see https://github.com/exasim-project/NeoFOAM/actions/runs/8990675598

Just for reference, I won't add this PR to the Changelog since it mainly changes our CI/CD
