Cleanup and enhance our export of the USD `extent` attribute. This does the following: - The existing `author_extents` function now uses recently added common code to write out the extents attribute - A new `author_extents` overload allows the use of Blender's native bounds for the types that support it. We now use this rather than asking USD to recompute it for us. - Meshes will now have their extents correctly written during animations - Curves will now have their extents written as they were not doing so prior to this PR - Hair, Lights, Points, and Volumes make use of the `author_extents` functions now Since Curves need their extents tested, this PR also moves the test from C++ to Python. Python tests allow for faster iteration, are more straightforward to write, and allow usage of the USD validator. Pull Request: https://projects.blender.org/blender/blender/pulls/132531
