Refactor JavaScript integration and improve code readability.

[nmerget]

Hey, I'm not into C++ so I did some try/error to fix the issues for the CI.

• Update .github/actions:

  • Moved the version to another workflow_call to reuse it for better maintenance (I going to open up an issue with my suggestions)
  • fixed issue with linux builds by removing werror=yes, which could be enabled again but Wno-error="cast-function-type" didn't work with SCONSFLAGS
  • removed dev_builds for linux because of the debugger

• removing/changing issues inside the ci:

  • some issues from this PR
  • disabling the debugger for now to make sure the pipeline won't fail

This branch should be squashed 👍

I approved the github actions. Been busy so if someone can continue the work on #156 that'll be amazing.

I think the js debugger is still being used so the build complains about needing it.

@fire the pipeline is running now

The first run takes very long especially for windows, I don't know if this is a normal behavior when building the editor. After the cache is initialized it is way faster.

Please squash this branch before merging, I added a lot of testing commits because of the pipeline, we don't need them in the history

I propose merging the open PRs to have a working 4.1 branch.
Afterward, I would like to structure the repo differently and add some extra workflow_calls to publish the artifacts: #165

Can you squash? I want to keep attribution intact

Thanks
