Refactor build process to enable auto-update of components

[neoaggelos]

Summary

Use a static build-scripts/components/$component/version file for each component version. Add a hack/update-component-versions.py to get the right latest versions based on configuration. Update CI to use those in all release branches and main

NOTE: This needs to be backported to 1.30 after merging for CI to work
