Geometry Nodes: Domain Size Node

The Domain Size node has a single geometry input and a selection for
the component type. Based on the component chosen, outputs containing
single values for the related domains are shown.

Mesh:
  - Point Count
  - Edge Count
  - Face Count
  - Face Corner Count
Curve:
  - Point Count
  - Spline Count
Point Cloud:
  - Point Count
Instances:
  - Instance Count
