Converter_DCDC: Add library_name as a parameter when building the footprint
This script can be useful for other devices different than DCDC converters.
For instance, it suits ACDC converters, as shown at: !953 (merged)
This MR adds support for a new parameter called library_name in the yaml file so the same script can be used for those as well.
This MR also renames the folder from Converter_DCDC to Converter_ACDC_DCDC, so it can be used for both types.
