This is part of the short term roadmap goal of simplifying the compositor workflow (see https://projects.blender.org/blender/blender/issues/134214). The problem is that many users don't know how to get started with compositing in Blender, even when they have used Blender for other areas, e.g. modeling. Note: although the solution makes compositor node trees reusable accross blend files, this is a nice side effect and not the main goal of the PR. This PR implements a "New" button that creates a new compositing node tree, and manages trees as IDs. This has following advantages: - Consistent with other node editors and other parts of Blender, therefore making it easier to getting started with compositing if users are familiar with shading or geometry nodes - Give users the ability to reuse the compositing node tree by linking or appending it. Note: The parameter "Use Nodes" is still present in this PR, but will be removed (in a backward compatible way) in a follow up PR.
