publish a JS library that provides many of the functions of agoric-cli

[turadg]

What is the Problem Being Solved?

We have JS code strewn about that spawns a process to call agoric or agops on the CLI. Since those are themselves implemented in JS, that's an unnecessary hop. Having it requires duplicating lots of logic, requires transforming all JS types to and from CLI arguments, and creates opportunities for bugs.

Description of the Design

Look at https://github.com/Agoric/agoric-3-proposals/blob/main/packages/synthetic-chain/src/lib/cliHelper.ts

Create a module that provides those functions directly from agoric-cli. It can be a subpath export of the package.

Alternately there could be a new package like agoric-commands that agoric-cli uses, but I think that's unnecessary separation. packages/agoric-cli provides the agoric package which has bin paths but can also provide module exports.

This could also help with,

• parity for capabilities of dapp-econ-gov and CLIs #7772
• testing API to extend ava functional tests to end-to-end context #8963
• make a functional testing package #10369

Security Considerations

Execution would run in the single JS process instead of spawning.
