Use raw PHP-WASM to run WP-CLI commands

Proposed Changes

Instead of instantiating Playground CLI, use a "raw" PHP-WASM instance to execute WP-CLI commands. In my quick benchmarks, this shows significantly better performance (wp option get takes 1.93s on this branch compared to 4.94s on the base branch).

This is essentially the same strategy that we already use on trunk. @bgrgicak very graciously helped me with some modifications to fix some issues we were having with network requests (wp plugin install commands would previously fail, for example).

Testing Instructions

1. Run npm run cli:build
2. Run node dist/cli/main.js wp --path PATH_TO_STUDIO_SITE
3. Ensure that the help contents are printed
4. Try a bunch of commands!

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

Based on a quick test, it works as expected. It's faster than 5 seconds, but still much slower than the native wp call. I guess it's acceptable given that it goes through PHP-WASM.

I noticed that table formatting is different. Here is the native wp:

% time wp plugin list --path=PATH

Why do we need to set up an SSL certificate?

[fredrikekelund]

I haven't tested without it, but WP-CLI sends network requests as part of several different commands, so I kind of assume this is needed

[ivan-ottinger]

I have tested running several commands, e.g. wp plugin install with the code commented out and they run without issues.

[wojtekn]

Nit: Would it make sense to use an array and a map here?

[fredrikekelund]

This is a matter of preference, IMO. I think the current approach reads clearly, and changing it to an array that we iterate over won't really make the code more compact

[wojtekn]

Should this be translated? If yes, do we need to use a domain?

[ivan-ottinger]

I haven't worked with PHP-WASM much yet, but the changes look good to me and the commands run well.

I have tested with several commands, including the ones that make network requests (e.g. wp plugin install) and all of them run as expected. 👍🏼

[fredrikekelund]

Thanks for the reviews, @wojtekn and @ivan-ottinger

table formatting

I'll take a look at this in a follow-up PR
