new client-utils package (#10407)

closes: #10168

## Description
Provide a new package, `client-utils`, as a home for utilities that are useful to clients of an Agoric chain. This doesn't currently use `@agoric/rpc` but over time some of it may be pushed down into that package. 

Related work…

- #9200 
This will be where those client factories are kept.

- #10369

This will solve most of what we need for functional testing. Some aspects are specific to the A3P synthetic chain (like account addresses and references to history) but most of what the tests are doing with the chain are operations that any client might do.

- #9109
- #8963

This will contribute to those goals.


### Security Considerations

Reduces authority needed to query chain (from child_process to fetch)

### Scaling Considerations
This is a big package, but it's not to be run on chain. Most client apps use some form of code shaking so they'll only take what they need.

### Documentation Considerations
Once this settles down it ought to be a part of docs.agoric.com

### Testing Considerations
The only test yet is a live one to make sure a query to Emerynet for Swingset params succeeds as expected, even under SES.

No package CI yet. Mostly it's refactoring of existing code so those uses serve as coverage. I do think this would benefit from some additional testing.

### Upgrade Considerations
Will never be on chain
