Delay imports of optional dependencies (#2485)

* Delay imports of optional dependencies

`qiskit_aer` and `scipy` were eagerly imported in the `utils.json` module
(with fallbacks for when they were not installed) which is imported
along with `import qiskit_ibm_runtime`. Here these imports are delayed
until JSON serialization or deserialization are attempted. In the
serialization case, the packages would have already been imported before
objects from them would need to be serialized any way.

Avoiding these imports saves roughly half a second (but the number
depends on the computer running the test).

* Use LazyImportTester for Scipy and Aer deserialization

* Fix typo in comments
