Directly use psutil to get total system memory
Currently Aer is using Qiskit's local_hardware_info() function which to determine the total amount of system memory which is used to compute the largest statevector the system can build. However, this function wasn't really intended to be used outside of Qiskit and also Qiskit is looking to remove the memory reporting (see: Qiskit/qiskit#11254). This commit just pivots to using psutil directly which is what qiskit is doing internally.

Added `psutil <https://pypi.org/project/psutil/>`__ as a dependency for | ||
Qiskit Aer. This is used to determine the amount of physical resources | ||
available. ``psutil`` is currently a dependency of Qiskit, which is a | ||
requirement for Qiskit Aer, so ``psutil`` was effectively already required | ||
for any ``qiskit-aer`` installation. But, as qiskit-aer is now using it | ||
directly is now a direct dependency for ``qiskit-aer``. |
