Summary
This is fix for issue #1878
Details and comments
requried_memory_mb function for statevector returns wrong value when number of qubits is very large because of overflow of 64 bits integer.
Now it returns SIZE_MAX value when number of qubits is too large so that Qiskit Aer can know memory is not sufficient for statvector/unitary/density matrix methods.
