Closes #11670: Add ability to optionally import DeviceType and ModuleType weight (#12512)

* 11670: Add optional weight to DeviceType import

This is 1 of 2 commits to address issue #11670

To maintain consistency, the import design of the DeviceType weight follows the
same pattern used for importing weight and weight units in DCIM Racks.

* Closes #11670: Add weight to ModuleType import

This is commit 2 of 2 to address and close #11670.

To maintain consistency, the import design of the ModuleType weight follows the
same pattern used for importing weight and weight units in DCIM Racks.

* Merge tests; misc cleanup
