This commit improves the performance of the node by up to 40% in some cases when there are only two input meshes, mainly by skipping the conversion to and from BMesh. When there are more than two input meshes (note the distinction from "Geometries", a geometry set can have many mesh instances), the performance is actually worse, since boolean currently always does self intersection in that case. Theoretically this could be improved in the boolean code, or another option is automatically realizing instances for each input geometry set. Another improvement is using multi-input sockets for the inputs, which removes the need to have a separate boolean node for every operation, which can hopefully simplify some node trees. The changes necessary for transforms in `mesh_boolean_convert.cc` are somewhat subtle; they come from the fact that the collecting the geometry set instances already gives transforms in the local space of the modifier object. There is also a very small amount of cleanup to those lines, using `float4x4::identity()`. This commit also fixes T87078, where overlapping difference meshes makes the operation not work, though I haven't investigated why. Differential Revision: https://developer.blender.org/D10599
