[CT-2146] Reusable Workflow for Branch/Release Cleanup

[emmyoop]

Since a lot has been automated and all of it doesn't create a PR, everything doesn't end up getting cleaned up. It would be nice to have a workflow that periodically cleaned up branches from automation. It's nice having the branches stick around past the end of the workflow for the times they need to be debugged.

Branches that need to be cleaned up:

pre-release/*
cutting_release_branch/*

Bonus:
Clean up stale branches - not sure if this is possible or how safe this is.
Remove releases in draft state - not the same as branches but makes sense to add it into this process and general repo cleanup

This applies to core and all adapters.
