Geometry Nodes: Get and set nodes for ID attribute

Browse Source 
These nodes allow accessing and changing the stable/random ID used
for motion blur with instances and stable randomness.

Since rB40c3b8836b7a, the stable ID is a built-in attribute, so to be
consistent and allow changing it in the node tree like other built-in
attributes, it has get and set nodes.
