Geometry Nodes: Expand the Boolean Math node

Currently the Boolean Math node only has 3 basic logic gates:
AND, OR, and NOT. This commit adds 6 additional logic gates
for convenience and ease of use.

- **Not And (NAND)** returns true when at least one input is false.
- **Nor (NOR)** returns true when both inputs are false.
- **Equal (XNOR)** returns true when both inputs are equal.
- **Not Equal (XOR)** returns true when both inputs are different.
- **Imply (IMPLY)** returns true unless the first input is true and
  the second is false.
- **Subtract (NIMPLY)** returns true when the first input is true and
  the second is false.
