OpenROAD is printing some warnings about missing CUTCLASS with LEF58_ENCLOSURE. LEF58_ENCLOSURE is not defined in the IHP Open PDK nor is this feature required for 130nm.

Suppress this warning to remove them from the logs.

@maliberty do you seen any issue with disabling this warning?

@osamahammad21 I don't think we care about DRC rules on the contact layer. Should we suppress this at the source rather than disabling it in ORFS?
