Blake Friedman c754755cd8 CLI supports ordering of tasks
Summary:
This gives Frameworks more control in selecting specific tasks and integrating the return types data in their UI.  For example piping `stdout` to the user or using packages like [Listr2](https://www.npmjs.com/package/listr2) to run tasks in parallel and show progress.

The ordering is suggestive (but also enforced by some assertions).  Frameworks are free to do what they want.

The order was implicit in the previous data structure with lists of Tasks, but made it difficult to tap into each async task.

I've also had to rework how we transpile the code if directly executed from the monorepo.  This keeps our:
- flow types valid,
- allows the core-cli-utils package to be built (to generate TypeScript types and a valid npm module), and
- allows direct transpiled execution as a yarn script.

@react-native/core-cli-utils

npm package

A collection of utilites to help Frameworks build their React Native CLI tooling. This is not intended to be used directly use users of React Native.

Usage

import { Command } from 'commander';
import cli from '@react-native/core-cli-utils';
import debug from 'debug';

const android = new Command('android');

const frameworkFindsAndroidSrcDir = "...";
const tasks = cli.clean.android(frameworkFindsAndroidSrcDir);
const log = debug('fancy-framework:android');

android
    .command('clean')
    .description(cli.clean.android)
    .action(async () => {
        const log = debug('fancy-framework:android:clean');
        log(`🧹 let me clean your Android caches`);
        // Add other caches your framework needs besides the normal React Native caches
        // here.
        for (const task of tasks) {
            try {
                log(`\t ${task.label}`);
                // See: https://github.com/sindresorhus/execa#lines
                const {stdout} = await task.action({ lines: true })
                log(stdout.join('\n\tGradle: '));
            } catch (e) {
                log(`\t ⚠️ whoops: ${e.message}`);
            }
        }
    });

And you'd be using it like this:

$ ./fancy-framework android clean
🧹 let me clean your Android caches
    Gradle: // a bunch of gradle output
    Gradle: ....
