Adds a python test script for the field inferencing mechanism in geometry nodes.

Tests various combinations of field-to-value and value-to-field combinations as well as unconnected base nodes. Zones are tested because they can require multiple passes to resolve, especially when nesting.

Testing is based on socket display shapes as a proxy for field type, since the field type is not exposed in RNA yet. Likewise, testing for red links caused by field dependencies can only be done indirectly currently, because such links are not actually made invalid by the inferencing code, and just drawn red by the editor.

This test should help with simplifying and extending the type inferencing code to future socket data types (grids, lists).

Test file attached for reference, will go to svn test files repo.

That looks very useful, thanks.

Can split up the individual sections into separate functions.
