Adding support for the AER MPS sim method and the ability to load an initial state.
Support for ExecutionInfo (state vector and density matrix): use a more direct integration approach with AER for statevec and density matrix sim to access the internal state w/o the need for JSON serialization (inefficient when there are many qubits).
Pull in the latest AER code.
