feature(cli): add custom inspector proxy based on `metro-inspector-proxy` (#21449)

# Why

Fixes ENG-7467

Related #21265

This is an initial draft to extend the CDP functionality of
`metro-inspector-proxy`.

# How

The implementation is slightly wonky around the `ExpoInspectorDevice`.
We want to reuse as much as possible from `metro-inspector-proxy`, but
we need to add stateful data per device.

In order to achieve that, we generate a new class type, based on the
user's installed `metro-inspector-proxy`. This makes everything less
readable but should include future updates in these classes.

As for the `ExpoInspectorProxy`, to avoid having to do the same thing,
we just wrap the whole inspector class and reuse what we can. The device
map is "linked" within the original inspector proxy instance, making the
data available to all methods that need it.

# Test Plan

Enable this feature with `EXPO_USE_CUSTOM_INSPECTOR_PROXY=1`

- [x] See tests for the actual CDP events we handle.
- [ ] See tests on the "bootstrapping code" to create the inspector and
devices.

feat(cli): auto setup typescript during start (#21475)

# Why

- Some users are confused about how to use the fully automated
TypeScript setup. It currently runs when you run `npx expo start` in a
project with `tsconfig.json` or any TypeScript file in the project.
- This change will run the TypeScript check continuously until
TypeScript is setup. This only applies to projects using Metro, and
currently is only run in `npx expo start`, and the run commands (when
the server is started in the current window, e.g. not headless mode).

issues, forums posts, or feature requests.

# How

- Fork the `runServer` function from Metro into the CLI so we can access
the Metro bundler instance directly.
- Use Metro's native file watching to observe new TypeScript files being
added to the project (within the observable files). This is fast and
ensures we don't accidentally block a thread that otherwise could've
been used for bundling.
- The TypeScript continuous check only runs once, if you remove
TypeScript and add it back in the same process, then nothing happens.
This is a performance optimization.
- If TypeScript is enabled while the process is running, the user will
not be prompted to install, the packages will just install in the
project. Failures will be displayed in the running process, and no more
attempts will be made.
- If TypeScript is detected on start then the existing system will be
used and the continuous check will be skipped, this means projects
already using TypeScript won't have any technical performance hit.

# Test Plan

- In a project without TypeScript:
- `npx expo`
- `touch tsconfig.json` or `mv index.js index.tsx` or `touch foo.tsx`
- TypeScript is automatically installed for the project.
- `EXPO_NO_TYPESCRIPT_SETUP` voids this behavior
- Added unit tests.

<!--
Please describe how you tested this change and how a reviewer could
reproduce your test, especially if this PR does not include automated
tests! If possible, please also provide terminal output and/or
screenshots demonstrating your test/reproduction.
