Make kitchen sink extension bundle the default

[adamziel]

Many reported issues are caused by Playground defaulting to the "light" PHP build. It saves 6MB of initial downloads, but it confuses new users with issues like broken image editing.

This PR changes the PHP bundle loaded by default to the "kitchen sink" one that ships with PHP extensions like finfo, GD, libxml. The change affects all APIs: Query, Blueprints, JS.

I don't like increasing the bundle size, but the light one is still an option for apps requiring less transfer and this should reduce the number of confused users and error reports.

Testing instructions

• Confirm the e2e tests passed.
• Go to local Playground
• Visit "/phpinfo.php" in Playground, confirm libxml is enabled (the
  output should contain --enable-xmlreader)
• Open Playground configuration modal, uncheck the additional PHP
  extensions, confirm your choice
• Confirm phpinfo.php now reports libxmls is disabled
• Interact with that modal again, turn on the PHP extensions, confirm
  libxml is loaded again

Let's give it a try!

Question: Do I need to update wp-now to see the new changes reflected in the VS Code Extension?

Most of the stress testing I've been doing is over there, or otherwise in local dev mode...

@flexseth this is unrelated to the offline tools. Only the https://playground.wordpress.net/ is affected. Both wp-now and the VS Code extension already come with all the PHP extensions built in.

I love this! We need to be mindful of the bundle size, but at the same time, our default behavior should be the same as PHP.

Understanding the "kitchen sink" #30

---

Here are the libraries I've found in the kitchen sink

PHP extensions

• gd - image editing
• finfo - get information about a file
• mbstring - file handling for local and remote?
• iconv - convert syntax on the fly?
• openssl - website security
• libxml, xml, simplexml, xmlreader, xmlwriter - import rich content
• dom - builds a document for the web browser..?

Other things in the kitchen sink?

Are there more utilities? In lieu of digging through the repo and trying to figure it out, figured I'd ask here :)

Also, are these good representations what the libraries do?

Are they all PHP extensions?
