MLBEDSW-3902: Fixes invalid op when cloning LeakyReLU operator
When running specific networks containing LeakyReLU operators, Vela would crash when cloning an ofm of a LeakyReLU operator.
In this procedure a deepcopy usage would try to copy an OperatorInfo object, which caused an error.
This was fixed by replacing the deepcopy usage with a copy and then manually referencing new instances of sensitive variables.
