Facade_Engine: Updated AW methods to handle Cavity UValue

[vgreen-BH]

Issues addressed by this PR

Closes #3315

Updated UValueOpeningAW and UValueSpandrelAW methods so that the Cavity UValue fragment is only applied to the center of the opening and not to the edges.

Test files

New check has been added under section 5 of the SpandrelAWTestFile: https://burohappold.sharepoint.com/:f:/r/sites/BHoM/02_Current/12_Scripts/03_Alpha/BHoM/BHoM_Engine/Facade_Engine/BHoM%20PR%20Test%20Files?csf=1&web=1&e=pf2Sja

Tested with test script and calculated values with spandrel are as expected.
