Add profiles for DeltaMaker 3D printers (#7712)

* Initial DM2 Profiles

Add profiles for DeltaMaker 3D printers

* Made changes to machine/fdm_machine_common.json and process/fdm_process_common.json to validate successfully using the Orca profile validator

* Update DeltaMaker 2.json

Corrected the capitalization of the file name.
