Move Provider import only under TYPE_CHECKING conditions (#1489)

### Summary

Qiskit 1.1 deprecated the Provider abstract class to be removed in 2.0
(planned for 1Q2025). In those cases where the class is used for only
typechecking purposes, the import should only happen when
`TYPE_CHECKING`. For the rest of the cases, I opened
#1488
