Not all devices have `native_gateset`

[vtomole]

What is happening?

These devices return None for the key native_gate_set when the target_info endpoint is called

1. QSCOUT
2. AQT

There might be others i'm missing. This issue is to fix all of them.

How can we reproduce the issue?

backend = provider.get_backend("sandia_qscout_qpu")
print(backend.target_info()['basis_gates'])
# prints
# None

What should happen?

Every device has a native gate set but we are currently not filling this info for all devices.
