[CLI] Move Blueprints v2 to Playground CLI package (#2364)

## Motivation for the change, related issues

Moves Blueprints v2 `.phar` file and the TypeScript module into the
`@wp-playground/cli` package and brushes up its logic.

This PR only moves dead code around. However, it also changes the
dependency graph of the project and affects the computed package.json
files, as in `@wp-playground/cli` now depends on `fs-ext`. For that
reason, there's also a change in the build machinery.

Also, `v2.spec.ts` uncovered a piping issue where polling after closing
the pipe caused a fatal error. Therefore, this PR adds an FS.isClosed()
check.

A part of #2281
