Sculpt: Improve performance when initializing face sets
Avoid conversion to `BMesh` for basic topology operations and data access.
Instead use a mesh map to retrieve the faces connected to each edge.
I observed performance improvements of 5x (600ms to 100ms) to 10x
(15s to 1s), with bigger changes for large meshes with more data layers
Switching to `std::queue` over Blender's `GSQueue` gave another
25% improvement.
