The general idea here is to wrap the `CurvesGeometry` DNA struct with a C++ class that can do most of the heavy lifting for the curve geometry. Using a C++ class allows easier ways to group methods, easier const correctness, and code that's more readable and faster to write. This way, it works much more like a version of `CurveEval` that uses more efficient attribute storage. This commit adds the structure of some yet-to-be-implemented code, the largest thing being mutexes and vectors meant to hold lazily calculated evaluated positions, tangents, and normals. That part might change slightly, but it's helpful to be able to see the direction this commit is aiming in. In particular, the inherently single-threaded accumulated lengths and Bezier evaluated point offsets might be cached. Ref T95355 Differential Revision: https://developer.blender.org/D14054
