Jacques Lucke ba82476ade Shader Nodes: support Integer Math node in EEVEE and Cycles

This adds the Integer Math node to shader nodes. It's the same node that
can already be used in Geometry Nodes and the Compositor.

While creating the regression test, I noticed that the integer math
implementation was a bit broken:
* The integer modulo (`%`) operator on the GPU is undefined for negative
  divisors (the added regression test showed that the behavior is not
  consistent across platforms).
* Use integer power function instead of using float implementation with
  casts.

The MaterialX implementation is omitted for now. I didn't look into it
in detail yet but for the Boolean Math node (#162798) it seemed like
some more work is needed there to support this type.
