Minimal changes to make Rigify use the current Action API (introduced in Blender 4.4) instead of the legacy API (removed in 5.0). Most of the refactoring consists of: - Find the right `Channelbag` - Replace operations on `Action` with operations on that `Channelbag`. I didn't manage to test all code, because some code paths are very hard to follow, and others seem to only be available for legacy rigs. This is part of #146586 Pull Request: https://projects.blender.org/blender/blender/pulls/147060
