Remove most pnpm hoisting, fix phantom deps (#24096)

We've long had pnpm's public hoisting disabled, but it also privately
hoists everything into `node_modules/.pnpm/node_modules/` for
compatibility with packages that have undeclared dependencies. Let's
disable most of that private hoisting and see what turns up.

Changes of note:

* We still hoist a bunch of eslint plugins (and one prettier plugin) as
  untangling that mess seems like enough work to put off for later.
* Only a few upstream packages have bugs that need working around:
  * `@mdx-js/loader`: mdx-js/mdx#2019
  * `@automattic/components`: Missing dep on `@wordpress/base-styles`.
	And the next version will probably be unusable for us due to added
	`i18n-calypso`.
  * `@automattic/popup-monitor`: Missing dep on `events`.
  * markdown-it`: Missing dep on `punycode`.
    markdown-it/markdown-it#230
  * `@samverschueren/stream-to-observable`: Outdated dep on `any-observable`.
    SamVerschueren/stream-to-observable#9
    Hacking around that should also fix p1649254510834369-slack-CBG1CP4EN.
  * `git-node-fs`: Missing peer dep on `js-git`.
    creationix/git-node-fs#8
* `fetch-mock`'s peer dep on `node-fetch` is optional, but only because
  they also allow running in-browser. It's required for node.
* Added `webpack-cli` alongside `webpack` everywhere to make sure
  p1650571211251179-slack-CBG1CP4EN is fixed. Dropped Webpack entirely
  from Boost instead though, they don't use it.
* Had our webpack-config package point to its own copy of
  `@babel/runtime` instead of making that a peer dep.
* Jetpack's extensions tests use a ton of `@wordpress/` packages that
  weren't being directly depended on.
