Tests: Geometry Nodes: Add regression tests for dynamics assets

Browse source 
Two simple tests for the dynamics assets. Also replace the specific
simulation test Python code with a test for a specific custom property
on the scene which tells the test code to run through the frame range
before applying modifiers.
