Update LakeshoreModel3xx pyvisa-sim YAMLs and tests

[trlemon]

Summary of Changes

1. Added missing commands to lakeshore_model335.yaml, lakeshore_model336.yaml, lakeshore_model372.yaml and rename some properties for clarity.
2. Added logic to lakeshore_base.py to bypass "blocking" functionality in blocking_t while in simulated mode.
3. Updated tests for Lakeshore Models 325, 335, 336, and 372 to use pyvisa-sim backend instead of mocked classes.
