Hans Goudey d3a1e9cbb9 Geometry Nodes: Multi-thread creation of selection from field
When boolean fields are evaluated and used as selections, we create
a vector of indices. This process is currently single-threaded, but
226f0c4fef added a more optimized multi-threaded version
of this process. It's simple to use this in the field evaluator.

I tested this with the set position node and a random
value node set to boolean mode on a Ryzen 2700x:
|              | Before  |  After  | Improvement |
| 10% Selected | 40.5 ms | 29.0 ms | 1.4x        |
| 90% Selected | 115 ms  | 45.3 ms | 2.5x        |

In the future there could be a specialized version for non-span
virtual array selections that uses `materialize` to lower virtual
call overhead.
