Renames "Sculpt Tool", "Vertex Paint Tool", ... to "Brush Type" in all cases. The name "tool" is overloaded, plus, there actually is a "Brush Tool" now. As a follow up to the assets project merge we can rename this in C++, added this to #116337 and opened #124201. At least rename it in the UI for a start.
