This patch adds two related nodes, a node for separating points
and mesh vertices based on a boolean attribute input, and a node
for creating boolean attributes with comparisons.

Here is a simple result on a subdivided sphere:

Point Separate T83059
The output in both geometries is just point data, contained in the mesh
and point cloud components, depending which components had data in the
input geometry. Any points with the mask attribute set to true will be
moved from the first geometry output to the second. This means that
for meshes, all edge and face data will be removed. Any point domain
attributes are moved to the correct output geometry as well.

Attribute Compare T83057
The attribute compare does the "Equal" and "Not Equal" operations by
comparing vectors and colors based on their distance from each other.
For other operations, the comparison is between the lengths of the
vector inputs. In general, the highest complexity data type is used
for the operation, and a new function to determine that is added.

Here is a more complicated use-case-like test file:
