Return the MemoryClass preferred by the Operator.
This is the MemoryClass that will be used to access the input and output vectors in the Mult() and MultTranspose() methods.
For example, classes using the MFEM_FORALL macro for implementation can return the value returned by Device::GetMemoryClass().
The default implementation of this method in class Operator returns MemoryClass::HOST.
