Update metadata of Primitives V2 (backport #12784)

[mergify]

Summary

This PR updates the metadata of Primitives V2 to be compatible with that of real devices.

• Added "version" and "circuit_metadata" to all classes
• StatevectorEstimator
  • Replace precision -> target_precision
• BackendEstimatorV2
  • Added shots
• BackendSamplerV2
  • Added shots

If I need to keep the compatibility of the metadata within Qiskit 1.*, I will revert the rename and removal.

I'm wondering StatevectorEstimator because it does not compute expectation values directly from the state vector not based on shots. So, there is not relevant information about shots and I did not add shots to StatevectorEstimator yet. If necessary, I can add something like shots=inf, for example.

Addresses Qiskit/qiskit-ibm-runtime#1724

Summary of discussion:

1. Update all metadata to match that of IBM devices.
   1-a. Shall we add shots=inf to StatevectorEstimator or not add shots?
2. Do not remove any existing metadata, i.e., precision of StatevectorEstimator and shots of StatevectorSampler.
