This implements the new way to attach curves to a mesh surface using a uv map (based on the recent discussion in T95776). The curves data block now not only stores a reference to the surface object but also a name of a uv map on that object. Having a uv map is optional for most operations, but it will be required later for animation (when the curves are supposed to be deformed based on deformation of the surface). The "Empty Hair" operator in the Add menu sets the uv map name automatically if possible. It's possible to start working without a uv map and to attach the curves to a uv map later on. It's also possible to reattach the curves to a new uv map using the "Curves > Snap to Nearest Surface" operator in curves sculpt mode. Note, the implementation to do the reverse lookup from uv to a position on the surface is trivial and inefficient now. A more efficient data structure will be implemented separately soon.
