Issue:
TensoredOp's to_matrix() returns a wrong value if coeff is not 1
### Environment

- **Qiskit Terra version**: 
  0.22.4
- **Python version**: 
  3.10.4
- **Operating system**: 
  Ubuntu 20.04.5 LTS


### What is happening?

`TensoredOp`'s `to_matrix()` returns a wrong value if coeff is not 1.

### How can we reproduce the issue?

Run the following code:
```
from qiskit.opflow import Plus, Zero
print((0.5 * (Plus ^ Zero)).to_matrix())
```

Then, the following will be printed:
```
[0.1767767+0.j 0.       +0.j 0.1767767+0.j 0.       +0.j]
```


### What should happen?

The following should be printed:
```
[0.35355339+0.j, 0.        +0.j, 0.35355339+0.j, 0.        +0.j]
```

### Any suggestions?

I think this problem is related to #9283.

Issue:
Parameter is_real seems not correct
### Environment

- **Qiskit Terra version**: 
- **Python version**: 
- **Operating system**: 


### What is happening?

`Parameter.is_real()` seems not correct.

### How can we reproduce the issue?

```python
>>> from qiskit.circuit import Parameter

>>> Parameter("a").is_real()
True
>>> (1j * Parameter("a")).is_real()
True
```



### What should happen?

Both should return `False` since we don't know whether `a` is real or not.

### Any suggestions?

Discussion:
Didn't we already discuss whether to use three-level logic here ? @Cryoris 
Yeah, we did 🙂 The plan was to do the same as sympy and symengine: return `None` while the expression is not bound, otherwise `True` or `False` accordingly

Issue:
`DensityMatrix.partial_transpose` does not preserve input dimensions
### Environment

- **Qiskit Terra version**: to be released in 0.24.0
- **Python version**: 3.10
- **Operating system**: MacOS


### What is happening?

The `partial_transpose` should return a density matrix of the same dimensionality as the input `DensityMatrix` object. When the dimensions are for systems different than qubits, the dimensions are currently not preserved. 

### How can we reproduce the issue?

For in the following example, the dimensions of the output density matrix ρ2 are (9,) but they should be (3,3).

```python
>>> import numpy as np
>>> from qiskit.quantum_info import Statevector, DensityMatrix
>>> ψ = Statevector(np.array([1,0,0,0,1,0,0,0,1])*1/np.sqrt(3),dims=(3,3))
>>> ρ1 = DensityMatrix(ψ)
>>> ρ1.dims()
(3, 3)
>>> ρ2 = ρ1.partial_transpose([0])
>>> ρ2.dims()
(9,)
```

### What should happen?

It should be an easy fix. The function should return:
```python
return DensityMatrix(rho, dims=self.dims())
```

instead of just:
```python
return DensityMatrix(rho)
```

### Any suggestions?

This can be seen in [VQD tutorial](https://qiskit.org/documentation/tutorials/algorithms/04_vqd.html) where it says it will print 3 energy values, but instead it's 3 lists

 See Qiskit/qiskit-tutorials#1471 which was to fix the deprecation and I had wondered why the change from using optimal_values as the output from what was checked in seemed fine. The above when its run from the latest VQD, as published out as html, is not though - so something changed since that was ran originally - hence this issue.

Issue:
Deprecate pkgutil namespace hooks in 0.23.0
### What should we add?

With the aer namespace migration to `qiskit_aer` and the pending deprecation of `qiskit-ibm-provider` we should look at removing the pkgtuil usage that adds hook points for namespace packaging. The hooks can be found here:

- https://github.com/Qiskit/qiskit-terra/blob/main/qiskit/__init__.py#L67-L69
- https://github.com/Qiskit/qiskit-terra/blob/main/qiskit/providers/__init__.py#L701-L704

As part of the 0.23.0 release we should deprecate these and remove them after the qiskit-ibmq-provider package is retired (which should be mid 2023 hopefully) probably as part of qiskit-terra 0.25.0. I don't think we can emit a warning on their usage so the best we can probably do is document it in the release notes for 0.23.0 that the removal is coming.

As an aside we can't technically block namespace expansion in an external package since python packaging supports it to some degree without any changes in the root package. But in practice that built-in mechanism is broken for a lot (if not most) of cases which is why we have the pkgutil hooks in place.

Test patch:
Repository: Qiskit/qiskit

Issue:
Remove code deprecated in 0.16 (released on October 15, 2020)
There is code released 33 month ago that needs to be removed.
 - qiskit/circuit/library/arithmetic/polynomial_pauli_rotations.py:228 (`num_ancilla_qubits`)
 
This includes:
- [ ] Remove deprecated code and tests (if they only check the deprecation raise)
- [ ] tag the PR as [`Changelog: Removal`](https://github.com/Qiskit/qiskit/labels/Changelog%3A%20Removal)
- [ ] create a release note in the category `upgrade:`. If you can include an example with an alternative for user to migrate to the new code, as this change might break users code.
