Build/Test Tools: Improve dev environment's CLI in speed, non-interactive usage, and argument handling.

* Start `cli` container when running `env:start`. This greatly speeds up calls to WP-CLI since the container is already running rather than having to start up for each call.
* Facilitate calls to `env:cli` in non-interactive context (non-TTY) to allow piping content into commands or use in shell scripts.
* Fix passing arguments to WP-CLI from `env:cli` so that arguments with spaces are passed as expected.
* Fix JSHint issues.

This aligns the wordpress-develop environment closer to wp-env. See https://github.com/WordPress/gutenberg/pull/50007.
