Deprecate `qiskit.Aer` and `qiskit.providers.aer` (#11439)

* Deprecate `qiskit.Aer` and `qiskit.providers.aer`

These were intended to be deprecated after the release of Aer 0.11, but
we apparently never actually got around to it.  This fully deprecates
the `qiskit.Aer` object, along with imports from `qiskit.providers.aer`,
as we will be removing those completely in Qiskit 1.0.

The namespace loaders in `qiskit.namespace` will also be removed in
Qiskit 1.0, but I have not marked these with deprecation warnings
because:
- we need to continue using them to effect the deprecations of the
  imports.
- they have never been documented as public interface, so are a private
  implementation detail.

All the use of `qiskit.providers.aer` in Terra and its tests is replaced
with `qiskit_aer`.  This name is only available from Aer 0.11, but in
practice, Aer 0.10 already does not work with Qiskit 0.46 (fails during
import), so this change does not affect the working set of Aer versions.

I haven't touched old imports of IBMQ, because that package is already
completely deprecated and we should be removing all attempted use of it
from Qiskit 1.0, because that code would never be able to succeed.

* Fix lint

* Deprecate running pulse jobs on fake backends

With Aer 0.13 removing the capability, this is not something we will be
able to support moving forwards.  This deprecates the functionality, in
preparation for its full removal in Qiskit 1.0.

* Restore old namespace checking to optionals finder

* Correct deprecation warning message
