chore: rework cluster-autoscaler Scaleway cloudprovider integration

[pablo-ruth]

What type of PR is this?

/kind feat

What this PR does / why we need it:

This PR reworks the Scaleway provider integration. We've updated the autoscaler's API calls to deprecate legacy infrastructure components and improve scaling performance. The new implementation optimizes our backend handlers, resulting in faster response times and more efficient cluster scaling operations.

Hi @pablo-ruth. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@pablo-ruth @louisportay do you build CA bits for Scaleway customers based on the upstream release branches for particular versions of Kubernetes or do you re-use the upstream images? Happy to backport these updates across the 1.31+ branches if that helps.

[louisportay]

We plan to reuse upstream images and sync release branches starting from 1.34.
So you don't have to worry about backporting (though it's nice asking :) )
